Find angle between A and B where, (a) `A = 2hati and B =- 6 hati` (b) `A = 6hatj` and `B =- 2hatk` (c) `A = (2hati = 3hatj)` and `B = 4 hatk` (d) `A = 4hati` and `B = (-3hati + 3hatj)` .

Text Solution

Verified by Experts

The correct Answer is:
A, B, C, D
(a) Antiparallel vectors
(b) Perpendicular vectors
(c ) A lies in x-y plane and B is along positive
z- direction. So, they are mutually perpendicular
vectors. (d) .
