COMSATS Physics — Vectors and Equilibrium
Vectors and Equilibrium is part of the Physics section of the NTS NAT-IE test COMSATS admits on (10 of the 90 MCQs). It breaks into 3 subtopics, and we hold 25 NAT-pattern practice MCQs on it, each with a written explanation. Tap a subtopic below to practise just that.

Vectors and Equilibrium MCQs from the NAT-pattern papers
Try each one before opening the answer. Each comes with a short explanation.
- Q1 · COMSATS Past Paper 07 · Vectors and Equilibrium
A body is in complete equilibrium when:
- A.both the net force and the net torque on it are zero
- B.its speed is increasing
- C.it moves in a circle at constant speed
- D.only the net force on it is zero
Show answer
Answer: A. both the net force and the net torque on it are zero — Complete equilibrium needs both translational (ΣF = 0) and rotational (Στ = 0) equilibrium.
- Q2 · COMSATS Past Paper 06 · Vectors and Equilibrium
A force of 10 N acts at 60° to the x-axis. What is its x-component?
- A.5 N
- B.0 N
- C.10 N
- D.8.66 N
Show answer
Answer: A. 5 N — Fₓ = F cos 60° = 10 × 0.5 = 5 N.
- Q3 · COMSATS Past Paper 04 · Vectors and Equilibrium
Two forces, each of magnitude F, act on a body at an angle of 180° to each other. Their resultant is:
- A.zero
- B.√2 F
- C.2F
- D.F
Show answer
Answer: A. zero — Equal forces in opposite directions cancel.
