NUST NET Physics — Oscillations
Oscillations is part of the FSc Physics course that NUST NET-Engineering draws on (Physics is 60 of the 200 MCQs). It breaks into 2 subtopics, and we hold 67 NET-pattern practice MCQs on it, each with a written explanation. Tap a subtopic below to practise just that.

Oscillations 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 · Oscillations
The time period of a simple pendulum (small oscillations) does NOT depend on:
- A.the mass of the bob
- B.the length of the string
- C.the acceleration due to gravity
- D.none of these; it depends on all three
Show answer
Answer: A. the mass of the bob — T = 2π √(L/g) contains no mass.
- Q2 · NUST NET Past Paper 08 · Oscillations
If the mass hanging on a spring is made 4 times larger, the time period of its oscillation becomes:
- A.4 times
- B.half
- C.2 times
- D.unchanged
Show answer
Answer: C. 2 times — T = 2π√(m/k), so T ∝ √m: √4 = 2.
- Q3 · NUST NET Past Paper 05 · Oscillations
The displacement of a particle in SHM is x = 0.05 sin(10πt) metres. Its frequency is:
- A.10 Hz
- B.10π Hz
- C.0.2 Hz
- D.5 Hz
Show answer
Answer: D. 5 Hz — ω = 10π = 2πf ⇒ f = 5 Hz.
