What is the angle between (vec(P)+vec(Q)...

What is the angle between `(vec(P)+vec(Q))` and `(vec(P)xxvecQ)?`

A

Zero

B

`(pi)/(2)`

C

`(pi)/(4)`

D

`pi`

Text Solution

Verified by Experts

The correct Answer is:
B
(b) `PxxQ`is perpendicular to the plane formed by P and Q P+Q lies in this plane Hence P+Q is perpendicular to `PxxQ`
