The vector sum of two forces is perpendicular to their vector differences. In that case, the force

A

Are equal to each other.

B

Are equal to each other in magnitude

C

Are not equal to each other in magnitude.

D

Cannot be predicted.

Text Solution

Verified by Experts

The correct Answer is:
B
`(vecA+vecB).(vecA-vecB)=0`
`rArrA^(2)-vecA.vecB+vecB.vecA-B^(2)=0`
`rArrA=B(because vecA.vecB=vecB.vecA)`
