Chapter 01: Vector Analysis & Dot/Cross Products

Paper 01

Core Concept & Orthogonality Condition

Two non-zero vectors Vector A and Vector B are perpendicular (orthogonal) if and only if their scalar dot product equals zero:

Vector A · Vector B = (Ax · Bx) + (Ay · By) + (Az · Bz) = 0

Solved BUET Admission Problem

Problem: Given Vector A = 2î + 3ĵ - k̂. Determine which of the following vectors is orthogonal to Vector A.

Step-by-step Shortcut Derivation:

Testing Option: Vector B = 1î - 1ĵ - 1k̂

A · B = (2 × 1) + (3 × -1) + (-1 × -1) = 2 - 3 + 1 = 0

✓ Hence Vector B is strictly orthogonal to Vector A.
