NUST NET Physics — Circular Motion
Circular Motion is part of the FSc Physics course that NUST NET-Engineering draws on (Physics is 60 of the 200 MCQs). It breaks into 3 subtopics, and we hold 80 NET-pattern practice MCQs on it, each with a written explanation. Tap a subtopic below to practise just that.

Circular Motion MCQs from the NET-pattern papers
Try each one before opening the answer. Each comes with a short explanation.
- Q1 · NUST NET Past Paper 07 · Circular Motion
A 2 kg body moves in a circle of radius 2 m at a constant speed of 4 m/s. The centripetal force on it is:
- A.8 N
- B.16 N
- C.32 N
- D.4 N
Show answer
Answer: B. 16 N — F = mv²/r = 2 × 16/2 = 16 N.
- Q2 · NUST NET Past Paper 08 · Circular Motion
The centripetal force on a body of mass m moving with speed v in a circle of radius r is:
- A.mv/r
- B.mv²/r
- C.mvr
- D.mr/v²
Show answer
Answer: B. mv²/r — F = mv²/r, directed towards the centre.
- Q3 · NUST NET Past Paper 05 · Circular Motion
The angular speed of the seconds hand of a clock is:
- A.π/30 rad/s
- B.π/60 rad/s
- C.2π rad/s
- D.π/1800 rad/s
Show answer
Answer: A. π/30 rad/s — ω = 2π/60 = π/30 rad/s.
