Question

A ball moves in a frictionless inclined table without slipping. The work done by the table surface on the ball is (A) positive (B) negative (C) zero (D) None of these

Tardigrade Admin · Accepted Answer

Force applied by the surface of the inclined table of the ball is normal reaction N. Work done by the table on the ball [Angle between normal reaction N and displacement s is 90° ] ∴ W=0

Force applied by the surface of the inclined table of the ball is normal reaction $N$ .
Work done by the table on the ball
[Angle between normal reaction $N$ and displacement s is $9 0^{\circ}$ ]
$∴$ $W = 0$
