The bob of a simple pendulum performs S.H.M. with period 
in air and with period 
in water. Relation between 
and 
is (neglect friction due to water, density of the material of the bob 
, density of water 
)
A
B
C

Text Solution
Verified by ExpertsThe correct answer is:
A
Let 
be the volume of the bob, then its weight in air is 
When immersed in water, buoyancy force, 
Effective weight in water, 
Effective acceleration will be
