Asseration : All surfaces shown in figur...

Asseration : All surfaces shown in figure are smooth. Block A comes down along the wedge B. Work done by normal reaction (between A and B) on B is positive while on A it is negative.
Reason : Angle between normal reaction and net desplacement of A is greater than `90^(@)` while between normal reaction and net displacement of B is less than `90^(@)`
.

A

If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.

B
