NUST NET Physics — Measurements
Measurements 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 50 NET-pattern practice MCQs on it, each with a written explanation. Tap a subtopic below to practise just that.

Measurements 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 · Measurements
The dimensions of Planck's constant are:
- A.[ML²T⁻²]
- B.[ML²T⁻¹]
- C.[MLT⁻¹]
- D.[ML²T⁻³]
Show answer
Answer: B. [ML²T⁻¹] — h = E/f has units J·s = kg m² s⁻¹, so [h] = [ML²T⁻¹].
- Q2 · NUST NET Past Paper 08 · Measurements
The number of significant figures in 0.00450 is:
- A.5
- B.3
- C.2
- D.6
Show answer
Answer: B. 3 — 0.00450 has 3 significant figures: 4, 5 and the trailing 0.
- Q3 · NUST NET Past Paper 05 · Measurements
Which of the following physical quantities is dimensionless?
- A.stress
- B.force
- C.strain
- D.pressure
Show answer
Answer: C. strain — Strain = change in length/original length, a ratio of two lengths, so it has no dimensions.
