The sum of two vectors A and B is at right angles to their difference. Then

A

Equal to each other

B

Equal to each other in a magnitude

C

Not equal to each other in magnitude

D

Cannot be predicted

Text Solution

Verified by Experts

The correct Answer is:
B
`(vec(A)+vec(B)).(vec(A)-vec(B))=0`
`A^(2)-B^(2)=0 rArrA^(2)=B^(2)`
`rArrA=B`
