Preparing for the Physics paper feels far less stressful once you practise the questions that actually tend to appear, rather than reading the whole book blindly. This page gives you a hand-picked set of NIOS Class 12 Physics 312 Objective Type Questions with answers for the 2026 session, prepared after studying past papers and going through the complete NIOS Physics textbook. Every objective format is covered, and you can check real samples below before you ask for the full booklet.

We have kept the language simple and the answers short, because most learners revising for the examination want clarity and not long theory. Each question here carries a correct answer and a one-line reason, so you understand why an option is right instead of memorising it. Treat this page as a quality check first, and then decide.
NIOS Class 12 Physics 312 Objective Type Questions for the 2026 Session
Physics 312 has a wide syllabus that runs from mechanics to modern physics, so knowing where to focus saves a lot of revision time. This collection pulls together the most repeated and most examinable ideas from every lesson into four objective formats. The aim is a resource that a learner can finish in a few focused sittings and still feel ready for the objective section of the paper.
The set is refreshed for the current session so the pattern matches what learners can expect in 2026. If you are also mapping the wider course before you revise, our NIOS Syllabus page lays out the subjects and structure in one place, which pairs well with the topic list further down.
How These NIOS Class 12 Physics Objective Type Questions Were Prepared
These NIOS Class 12 Physics Objective Type Questions were not written in a hurry or copied from one guide. Our team studied several years of question papers to see which concepts return again and again, then read through the complete NIOS Physics textbook lesson by lesson to make sure nothing important was left out. Only after that did we frame the questions, so each one reflects both the book and the real examination style.
To keep the practice realistic, we cross-checked the recurring patterns against the actual papers on our NIOS Previous Year Question Paper collection. That comparison is what shapes the four formats you see here, namely multiple choice, fill in the blanks, true and false, and match the following.
The four objective formats you get for every chapter
Multiple choice questions train quick recognition of the correct option. Fill in the blanks test exact terms and units. True and false statements catch the small misconceptions that lose marks. Match the following builds links between laws, formulae and their meaning. Together these formats mirror the objective portion of the Physics 312 paper closely.
Chapter Wise List of NIOS Physics 312 Topics Covered
The full booklet covers all eighteen lessons of the Physics 312 course. The table below lists every chapter with its NIOS lesson code and the core idea it deals with, so you can jump straight to the topics you find hardest. Sample questions later on this page are drawn from a few of these lessons.

Sample NIOS Physics 312 Multiple Choice Questions
Here are a few multiple choice samples taken directly from the booklet, drawn from more than one lesson so you can judge the range. Each carries the correct option and a short reason. These are exact extracts, kept word for word from the source.
Laws of Motion
1. Which physical quantity is the best measure of the inertia of an object?
A) Volume
B) Acceleration
C) Mass
D) Force
Answer: C) Mass
Explanation: Inertia is the tendency of an object to resist changes in motion. The mass of a body quantifies its inertia — higher mass implies greater inertia.
Laws of Motion
2. A marble rolls on a frictionless horizontal surface indefinitely. This illustrates:
A) Newton's third law
B) Inertia of direction
C) Newton's first law
D) Kinetic energy conservation
Answer: C) Newton's first law
Explanation: In the absence of net external force, an object continues in its state of uniform motion. This is Newton's First Law of Motion.
Electric Charge and Electric Field
3. Coulomb's force acts between:
A) Two neutral bodies
B) Two moving charges only
C) Two static point charges
D) Two dipoles only
Correct Answer: C
Explanation: Coulomb's law is valid only for static (stationary) point charges.
Electric Charge and Electric Field
5. Coulomb force in air is stronger than in water because:
A) Water has high density
B) Water has low permittivity
C) Water has high permittivity
D) Air molecules are polar
Correct Answer: C
Explanation: Coulomb's force decreases with increasing permittivity; water has a higher permittivity than air.
Sample Physics 312 Fill in the Blanks Questions
The fill in the blanks format checks whether you remember the exact term, unit or value. These samples come from the Work, Energy and Power lesson and appear here exactly as they do in the booklet.
Work, Energy and Power
1. Work done by a force is defined as the dot product of __________ and __________.
Answer: Force; displacement
Explanation: Work W=F⃗⋅d⃗ , meaning it's the scalar product of two vectors.
Work, Energy and Power
2. If the angle between force and displacement is 90°, then the work done is __________.
Answer: Zero
Explanation: Because cos 90°= 0, hence W = Fd cos 90°= 0.
Work, Energy and Power
3. The SI unit of work is __________, and its dimensional formula is __________.
Answer: Joule; [ML²T⁻²]
Explanation: 1 Joule = 1 N × 1 m, and work = force × distance → [MLT⁻²] × [L] = [ML²T⁻²].
Work, Energy and Power
7. The unit of energy used in electrical appliances is __________, and 1 such unit equals __________ joules.
Answer: Kilowatt-hour; 3.6 × 10⁶
Explanation: 1 kWh = 1000 W × 3600 s = 3.6 × 10⁶ J
Sample Physics 312 True and False Statements
True and false statements are where careless mistakes happen, because a single word changes the meaning. Read each one slowly. These samples are from the Laws of Motion lesson and are reproduced without any change.
Laws of Motion
1. A body cannot be in uniform motion if there is no net external force acting on it.
False
Explanation: Newton's First Law states that a body remains in uniform motion in a straight line unless acted upon by a net external force. Thus, motion can exist without a force.
Laws of Motion
3. A marble on a perfectly smooth horizontal floor would never stop moving unless a force is applied.
True
Explanation: On a frictionless surface, no net force implies no change in motion. According to Newton's First Law, the marble continues indefinitely.
Laws of Motion
9. Action and reaction forces always act on the same object.
False
Explanation: They act on different objects. That's why they do not cancel out.
Laws of Motion
12. Rocket propulsion works on the principle of Newton's Third Law and conservation of momentum.
True
Explanation: Thrust is produced as gases are ejected downward; rocket moves upward. Total momentum of the system is conserved.
