A simple pendulum has a time period T in vacuum. Its time period when it is completely immersed in a liquid of density one-eight of the density one-eight of density of material of bob is :
Given,
Density of liquid / density of bob
Time period of simple pendulum,
Weight in liquid = weight in vaccume – buoyancy force.
(dB?V)a=(dB?V)g−(dL?V)g (Where, V= volume of bob)
Due to buoyancy, downward acceleration become,
Time period in vacuume / time period in liquid
Hence, time period in liquid is
