`vecA and vecB` are two vectors and `theta` is the angle between them, if `|vecA xx vecB|=sqrt(3)(vecA.vecB)` the value of `theta ` is:-

A

`45^@`

B

`30^@`

C

`90^@`

D

`60^@`

Text Solution

Verified by Experts

The correct Answer is:
D
`|vecAxxvecB|=sqrt3(vecA.vecB) rArr AB sin theta = sqrt3 AB cos theta`
`rArr tan theta =sqrt3 rArr theta =60^@`
