What is the angle between `vec(P)` and the resultant of `(vec(P)+vec(Q))` and `(vec(P)-vec(Q))` ?

A

zero

B

`tan^(-1) (p//Q)`

C

`tan ^(-1)(Q//p)`

D

`tan^(-1)(P-Q)//(P+Q)`

Text Solution

Verified by Experts

The correct Answer is:
A
(a) Resultant of `(P+Q)and (P-Q)is P+Q+P-Qor 2P`
which is parallel to p.
So angles between P and 2P will be zero.
