About Physics MCQs
This Physics section sits under Everyday Science and covers the topics most often tested in general knowledge papers. You will find questions on optics, such as the focal point of a lens, on electricity and magnetism, including inductive coils and AC circuits, and on modern physics, such as photons, excited atoms and the depletion region of a semiconductor junction. Dimensional analysis also appears often, for example the dimensions of power and elastic modulus, along with basic cosmology like the expanding universe.
General science papers in Pakistan, India and Bangladesh regularly include short physics items that reward clear definitions rather than long calculations. Knowing what an electron is, how lenses form images or which quantity has which SI unit can earn quick marks. Practising a wide spread of these MCQs builds recall of standard terms, helps you spot distractor options and prepares you for the mixed science sections found in CSS, PPSC, SSC and BCS preliminary tests.
Key facts to remember
- Electrons are negatively charged particles that orbit the nucleus of an atom.
- A photon is a quantum, or discrete packet, of electromagnetic energy.
- The dimensional formula of power is ML²T⁻³, meaning work done per unit time.
- A convex lens converges parallel rays of light to a real focal point.
- The SI unit of electric resistance is the ohm.
- The speed of light in a vacuum is about 3 × 10⁸ metres per second.

How to prepare for Physics MCQs
- Memorise the SI units and dimensional formulas of common quantities such as force, work, power and pressure, since they appear repeatedly.
- Draw quick ray diagrams for convex and concave lenses and mirrors to answer image position questions without guessing.
- Learn the charge, mass and location of the electron, proton and neutron, as atomic structure items are very common.
- Group your revision by branch, for example optics, electricity and modern physics, and attempt a short MCQ set after each branch.
Frequently asked questions
What are the most important topics in Physics MCQs?
The most frequently tested topics are units and dimensions, light and lenses, electricity and magnetism, atomic structure and basic modern physics such as photons and semiconductors. General science papers also include simple questions on motion, heat and sound, so a broad but concept-focused revision works best.
How many Physics MCQs are on MCQs360?
MCQs360 currently has 999 Physics MCQs in the Everyday Science section. Each question shows its correct answer instantly, and the whole collection is free to practise without signing up, so you can work through it in short daily sessions.
Which exams ask Physics MCQs at general science level?
Physics questions appear in the general science and everyday science papers of CSS, PMS, PPSC and NTS tests in Pakistan, SSC CGL, RRB NTPC and UPSC prelims in India, and the BCS preliminary exam in Bangladesh. Armed forces initial tests also include basic physics items.
What is a photon?
A photon is the smallest discrete packet, or quantum, of electromagnetic radiation such as light. It has no rest mass, travels at the speed of light in a vacuum and carries energy proportional to its frequency, given by E = hf, where h is Planck's constant.
