can the work done be zero
Asked by prachidesai7000 | 26th Jul, 2009, 12:57: PM
Yes, work done can be zero under two conditions :-
1. When the displacement is zero.
2. When the angle between the applied force and the direction of displacement is 90o.
Example ;- 1. Work done by electrostatic force of nucleus on electron when it relvolves round the nucleus is zero.
