Two vectors under vector multiplication have magnitude one, if angle between them is of

A

`45^(@)`

B

`90^(@)`

C

`60^(@)`

D

`120^(@)`

Text Solution

Verified by Experts

The correct Answer is:
B
Vector multiplication of `vec(P)` and `vec(Q)` are
`P.Q sin theta = 1`
When, `sin theta = 1`
`rArr theta = 90^(@)`
