Q. Work done by a simple pendulum in one complete oscillation is:
JIPMER
JIPMER 1998
A
$ \frac{1}{2\pi }\frac{\sqrt{l}}{g} $
B
$ \upsilon \,\sin \frac{\theta }{2} $
C
$ \sqrt{mg} $
D
zero
Solution:
From the formula the work done is the product of force and displacement. As displacement after one complete oscillation of simple pendulum is zero. Hence, work done will also be zero.
