Which of the following is the unit vector perrpendicular to A and B?

A

`(overset(rarr)A xx overset(rarr)B)/(AB sin theta)`

B

`(overset(rarr)A xx overset(rarr)B)/(AB cos theta)`

C

`(overset(rarr)A xx overset(rarr)B)/(|overset(rarr)A.overset(rarr)B|)`

D

`(overset(rarr)A xx overset(rarr)B)/(|overset(rarr)A||overset(rarr)B|)`

Text Solution

Verified by Experts

The correct Answer is:
a
The required unit vector is `(overset(rarr)A xx overset(rarr)B)/(|overset(rarr)A xxoverset(rarr)B|)=(overset(rarr)A xx overset(rarr)B)/(AB sin theta)`
