Class 11 FSc Physics Practice MCQs — Free Online Practice
You are IN first year now — these are the HSSC Part-1 topics you are actually studying. Below are 8 Physics MCQs with worked answers, drawn from our bank of 14. First-year physics shared by the older FSc Part-1 book and the current Punjab edition — vectors, projectiles, work-energy, circular motion, fluids, waves, optics, thermodynamics and electricity.
How this fits your first year
This is course practice, not an entry paper: first-year topics at Part-1 depth, one bank each for Maths, Physics and Chemistry. Topics follow the published FSc Part-1 curricula — restricted to the chapters the older FSc Part-1 books and the current Punjab edition keep in common, so both cohorts get their subjects. Each college or board's own syllabus is the final word on any year's exact list.

Free sample Physics MCQs (with answers)
1. The time period of a simple pendulum of length l is:
Oscillations & Waves · easy
- A. √(2πl/g)
- B. 2πl/g
- C. 2π√(g/l)
- D. 2π√(l/g)
Correct answer: D
T = 2π√(l/g): longer pendulums are slower. The g/l variant inside the root is the inverted formula — a common slip that predicts shorter periods for longer strings.
2. A force of 10 N acts at 60° to a displacement of 2 m. The work done by the force is:
Work, Energy & Power · easy
- A. 10 J
- B. 40 J
- C. 20 J
- D. 5 J
Correct answer: A
W = F·d·cos θ = 10 × 2 × cos 60° = 20 × 0.5 = 10 J. Using the angle directly (20 J) ignores that only the component ALONG the displacement works.
3. Two tuning forks of frequency 440 Hz and 444 Hz are sounded together. The beat frequency heard is:
Oscillations & Waves · easy
- A. 4 Hz
- B. 8 Hz
- C. 884 Hz
- D. 2 Hz
Correct answer: A
Beat frequency = |f₁ − f₂| = 444 − 440 = 4 Hz — the loudness swells and fades 4 times per second. Beats come from superposition, never from adding the frequencies.
4. For an isothermal process of an ideal gas:
Heat & Thermodynamics · medium
- A. no work is done
- B. no heat flows
- C. the pressure stays constant
- D. the internal energy change is zero
Correct answer: D
Isothermal = constant temperature, and for an ideal gas internal energy depends only on temperature — so ΔU = 0. Heat and work may both flow; they cancel each other (Q = W).
5. A projectile is launched with speed v at 45° to the horizontal. Its horizontal range R is:
Force & Motion — Projectiles · medium
- A. 2v²/g
- B. v²/2g
- C. v² sin 45°/g
- D. v²/g
Correct answer: D
Range formula R = v²·sin 2θ/g; at θ = 45°, sin 2θ = sin 90° = 1, so R = v²/g — the maximum range of any launch angle, which is exactly why 45° is special.
6. Bernoulli’s equation, relating pressure and speed along a streamline, is a statement of the conservation of:
Fluid Dynamics · easy
- A. mass
- B. momentum
- C. energy
- D. charge
Correct answer: C
Bernoulli’s equation sums pressure, kinetic energy per unit volume and potential energy per unit volume — a constant, i.e. energy conservation for flowing fluid. Mass conservation is the CONTINUITY equation, its partner.
7. The magnetic force on a straight current-carrying wire of length L making angle θ with a field B is:
Electromagnetism · easy
- A. BI/L
- B. BIL sin θ
- C. BIL²
- D. BIL cos θ
Correct answer: B
F = BIL sin θ: zero when the wire lies along the field (θ = 0), maximum when it is perpendicular (θ = 90°, F = BIL) — the geometry the sine captures.
8. Two forces of magnitude F act on a point at 60° to each other. The magnitude of their resultant is:
Vectors & Equilibrium · medium
- A. F
- B. F/2
- C. F√3
- D. 2F
Correct answer: C
Parallelogram law: R = √(F² + F² + 2F·F·cos 60°) = √(2F² + F²) = F√3. The 2F trap would hold only for parallel (0°) forces.
