can the work done be zero
Asked by prachidesai7000 | 26 Jul, 2009, 12:57: PM
answered-by-expert Expert Answer

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.

Two blocks of mass m=5kg and M=10 kg are connected by a string passing over a pulley B as shown. Another string connects the centre of the pulley B to the floor and passes over another pulley A as shown. An upward force F is applied at the centre of pulley A. Both the pulleys are massless. Find the acceleration of both the blocks if 1) F=100N.  2)F=500N

In the arrangement shown in the figure, a heavy pulley of mass M is suspended from a spring of stiffness constant K and the mass m is suspended from a string tightly wound on the pulley. If the mass m is given a small downward displacement and released, find the time period of small oscillations (Take pulley as Disc) and string does not slips on the pulley.
