If the magnitude of the vector product |...

If the magnitude of the vector product `| vec(A) xx vec(B)|` of two vector is equal to the magnitude of their scalar product `| vec(A) . vec(B)|` , then the angle between `vec(A) and vec(B)` is `……….`

A

`pi/3`

B

`pi/6`

C

`pi/4`

D

`pi/2`

Text Solution

Verified by Experts

The correct Answer is:
C
`| vec (A) xx vec(B)| = | vec(A) . Vec(B)|`
`AB sin theta = AB cos theta `
` :. tan theta = 1 `
` :. theta = pi/4`
