Given that `veca * vecb = 0` and `veca xx vecc = 0` Then the angle between `vecb and vecc` is

A

`0^(@)`

B

`45^(@)`

C

`90^(@)`

D

`180^(@)`

Text Solution

Verified by Experts

The correct Answer is:
c
`veca * vecb = 0`, So `veca` perpendicular to `vecb, veca xx vecc = 0`, So `veca` parallel to `vecc`. Hence `vecb` is perpendicular to `vecc`.
