Question

The vectors (A + B) and (A – B) are at right angles to each other. This is possible under the condition, A = B, A . B = 0, A . B = 1, A × B = 0

MARKS App · Accepted Answer

Vectors (A + B ) and (A – B) are at right angle to each other, therefore A + B . A - B = 0 A . A + B . A - A . B - B . B = 0 A + B A c o s θ - A B c o s θ - B 2 = 0 A 2 = B 2 Hence, A = B
