Question

Give any two examples in which no work is done on a body even through a fore act on it.​

Answer 1

1)When a force acts but there is no displacement in the body.

e.g.-  A boy pushing a wall

2)When the force acts at an angle of 90 degrees to the displacement.

e.g.- A man moving with a suitcase in his hand- there will be no work done on the suitcase.
