A magnitude of vector vecA,vecB and vecC...

A magnitude of vector `vecA,vecB` and `vecC` are respectively `12, 5` and `13` units and `vecA+vecB=vecC` then the angle between `vecA` and `vecB` is

A

5 unit due east

B

25 unit due west

C

5 units due west

D

25 units due east

Text Solution

Verified by Experts

The correct Answer is:
B
`vecA = 5` units due east
`therefore - 5hatA = -5`(5 units due east)
` = - 25` units due east = 25 units due west
