Question

Choose the correct option
Question:- If two non parallel vectors a and b are equal in magnitude, then magnitude of a-b and a+b will be :
Options:-
(A) parallel to each other
(B) perpendicular to each other
(C) anti-parallel to each other
(D) inclined at an angle less than 90 degree​

Answer 1

hi mate here iš ur answer

Vectors a-b & a+b will be mirror images of each other with vector a as mirror axis.

Magnitude of each of the vectors a+b & a-b is

a*(2)^1/2.

Angles of a+b vector & a-b vector are +45 & -45 degrees resp. with respect to vector a.

Answer 2

Answer:B

Explanation:

(A-B) (A+B)

A^2-B^2

Therefore they are perpendicular
