If for two vectors `vec(A)` and `vec(B), vec(A)xxvec(B)=0`, the vectors

A

Are perpendicular to each other

B

Are parallel to each other

C

Act at an angle of `60^(@)`

D

Act at an angle of `30^(@)`

Text Solution

Verified by Experts

The correct Answer is:
B
`vec(A)xxvec(B)= 0 :. Sin theta= 0 implies theta= 0^(@)`
Two vectors will be parallel to each other.
