Question

If |A+B|= |A-B| then the vectors are a) Parallel to each other b)Inclined at 450 to each other c)Perpendicular to each other d)Inclined at 600 to each other.

Answer 1

Answer:

option C perpendicular to each other

Explanation:

if two vectors are perpendicular to each other then sub and addition of vectors are equal because cos90 = 0

$resultand = \sqrt{ {a}^{2} + {b}^{2} + 2ab \cos}$
