If `|vecA+vecB|=|vecA|+|vecB|`, then angle between `vecA` and `vecB` will be

A

`90^@`

B

`120^@`

C

`0^@`

D

`60^@`

Text Solution

Verified by Experts

The correct Answer is:
C
Resultant of two vectors `vecA` and `vecB` can be given by `vecR=vecR+vecB`
`vecR=vecA+vecB`
`|vecR|=|vecA+vecB|=sqrt(A^(2)+B^(2)+2ABcostheta)`
If `theta=0^(@)`, then `|vecR|=A+B=|vecA|+|vecB|`
