1.

The vector sum of two forces is perpendicular to their vector differences. In that case, the forceA. Are equal to each other.B. Are equal to each other in magnitudeC. Are not equal to each other in magnitude.D. Cannot be predicted.

Answer» Correct Answer - B
`(vecA+vecB).(vecA-vecB)=0`
`rArrA^(2)-vecA.vecB+vecB.vecA-B^(2)=0`
`rArrA=B(because vecA.vecB=vecB.vecA)`
