A simple pendulum of length 1 m has a bob
of mass 10 g. Find the work done in moving
the pendulum from a vertical position to a
horizontal position. Take g = 10 m/s square.

Answer:
Length of simple pendulum =1m
Mass =1wgm=0.1kg
It is displaced through as angle of 60 for vertical
Height of pendulum at starting position = length (1−ws60)
=1(1−0.5)
=0.5m
Potential energy =mgh=0.1×10×0.5=0.55
when it is released and it reaches mean position its potential energy at starting point is converted to kinetic energy.
so K.E. of bob at mean position =0.55.
Hence, the answer is 0.55.
