The angle between vector `(overset(rarr)A-overset(rarr)B)` and `(overset(rarr)B xx overset(rarr)A)` is :

A

`60^(@)`

B

`90^(@)`

C

`120^(@)`

D

`45^(@)`

Text Solution

Verified by Experts

The correct Answer is:
B
`overset rarr A- overset rarr B` will give us a new vector whose directon in the plane of A and B.
`overset rarr A xx overset rarr B` will give us a new vector whose direction perpendicular to A and B.
Then the angle between `overset rarr A - overset rarr B and overset rarr Axx overset rarr B ` will
