NUST NET Physics — Physics of Solids
Physics of Solids is part of the FSc Physics course that NUST NET-Engineering draws on (Physics is 60 of the 200 MCQs). It breaks into 1 subtopic, and we hold 34 NET-pattern practice MCQs on it, each with a written explanation. Tap a subtopic below to practise just that.

Physics of Solids 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 · Physics of Solids
The SI unit of Young's modulus is the same as that of:
- A.force
- B.pressure
- C.strain
- D.energy
Show answer
Answer: B. pressure — Y = stress/strain; strain has no unit, so Y has the unit of stress, N/m² (Pa).
- Q2 · NUST NET Past Paper 08 · Physics of Solids
A wire of Young's modulus 1 × 10¹¹ Pa is under a tensile stress of 2 × 10⁸ Pa. The strain in the wire is:
- A.2 × 10⁻³
- B.5 × 10²
- C.2 × 10¹⁹
- D.5 × 10⁻⁴
Show answer
Answer: A. 2 × 10⁻³ — Strain = stress/Y = 2 × 10⁸/1 × 10¹¹ = 2 × 10⁻³.
- Q3 · NUST NET Past Paper 05 · Physics of Solids
A steel wire (Y = 2 × 10¹¹ Pa) is 1 m long with cross-sectional area 1 mm². A load of 200 N stretches it by:
- A.0.1 mm
- B.10 mm
- C.1 mm
- D.2 mm
Show answer
Answer: C. 1 mm — ΔL = FL/(AY) = 200 × 1/(10⁻⁶ × 2 × 10¹¹) = 10⁻³ m = 1 mm.
