1.	Show that for a simple pendulum, the work done by the tension of the string becomes zero during its oscillation.
Answer» Solution :Work done by a force is the productof the force with the component of the displacement of THEDISPLACEMENT along the force. In the CASE of an OSCILLATING siple pendulum, tension in the bob. HENCE, the component of displacement of the bob is zero in the direction of tension, therefore, the tension does notdo anywork.
