Q. 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
Explanation
(c) Work done on the ball by the table surface is the work done by the frictional force. Since a ball moves on a frictionless inclined table (or smooth surface), therefore frictional force is zero. Hence the work done on the ball by the table surface is zero
