ECAT Physics MCQs by Chapter: Mechanics, Electricity & Modern Physics
Chapter-wise ECAT Physics practice — Mechanics, Electricity & Magnetism, and Modern Physics, the three highest-weight areas, with sample MCQs for each.
ECAT Physics draws heavily from three chapters: Mechanics, Electricity & Magnetism, and Modern Physics. Rather than one flat "ECAT Physics MCQs" post, here's a chapter-by-chapter sample so you can target your revision precisely.
Chapter: Mechanics

- C) 10.8 m/s²
- D) 11.2 m/s²
2. Momentum is defined as the product of:
- A) Force and time
- B) Mass and velocity ✅
- C) Mass and acceleration
- D) Force and distance
3. Which quantity remains conserved in a perfectly elastic collision?
- A) Only momentum
- B) Only kinetic energy
- C) Both momentum and kinetic energy ✅
- D) Neither
Chapter: Electricity & Magnetism
4. According to Ohm's Law, if resistance is doubled while voltage stays constant, current will:
- A) Double
- B) Stay the same
- C) Halve ✅
- D) Quadruple
5. The magnetic field around a straight current-carrying wire forms:
- A) Straight lines parallel to the wire
- B) Concentric circles around the wire ✅
- C) A single point

Chapter: Modern Physics
7. The photoelectric effect was explained by Einstein using the concept of:
- A) Wave-only nature of light
- B) Quantized light energy (photons) ✅
- C) Sound waves
- D) Magnetic fields
8. An alpha particle consists of:
- A) 2 protons and 2 neutrons ✅
- B) 2 protons and 2 electrons
- C) 1 proton and 1 neutron
- D) 4 neutrons
9. Nuclear fission involves:
- A) Combining two light nuclei into one
- B) Splitting a heavy nucleus into smaller nuclei ✅
- C) Electron capture only
- D) Radioactive decay of a single proton
Why This Split Matches the Real Paper
ECAT Physics rewards depth in these three chapters more than breadth across every topic in the FSc syllabus — a candidate solid in Mechanics, Electricity & Magnetism, and Modern Physics is well-positioned even without exhaustive coverage of every minor topic.
