`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

`90^(@)`

B

`60^(@)`

C

`45^(@)`

D

`30^(@)`

Text Solution

Verified by Experts

The correct Answer is:
B
`:' |vecA xx vecB|=sqrt(3)(vecA. vecB)`
` :. AB sin theta =sqrt(3) AB cos theta `
`=tan theta =sqrt(3)implies theta =60^(@)`
