COMSATS Mathematics — Vectors
Vectors is part of the Mathematics section of the NTS NAT-IE test COMSATS admits on (10 of the 90 MCQs). It breaks into 1 subtopic, and we hold 11 NAT-pattern practice MCQs on it, each with a written explanation. Tap a subtopic below to practise just that.

Vectors MCQs from the NAT-pattern papers
Try each one before opening the answer. Each comes with a short explanation.
- Q1 · COMSATS Past Paper 05 · Vectors
If a · b = 0 for two non-zero vectors a and b, then a and b are:
- A.parallel
- B.in opposite directions
- C.equal
- D.perpendicular
Show answer
Answer: D. perpendicular — a · b = |a||b| cos θ = 0 → cos θ = 0 → θ = 90°.
- Q2 · COMSATS Past Paper 02 · Vectors
The magnitude of the vector 4i − 4j + 7k is:
- A.7
- B.81
- C.9
- D.15
Show answer
Answer: C. 9 — |v| = √(16 + 16 + 49) = √81 = 9.
