If `vec a +vec b =vec c and |vec a|=|vec b| = |vec c |` find the angle between `veca and vec b`

A

`(pi)/(4)`

B

`(pi)/(2)`

C

`pi`

D

0

Text Solution

Verified by Experts

a and b vectors are in the same direction. B and c are in the opposite direction.
`implies`a and c are in opposite directions.
`therefore` Angle between a and c is `pi`.
