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

A

A =B

B

A= 2B

C

B = 2A

D

`vecA` and `vecB` have the same direction

Text Solution

Verified by Experts

The correct Answer is:
A
`(vecA +vecB)(vecA -vecB) = 0`
`vecA.vecA+vecB.vecA-vecA.vecB-vecB.vecB=0`
`" "A^(2)- B^(2) =0`
`rArr" "A^(2)= B^(2)`
`rArr" "A =B`
