A solid cylindrical block of mass 4 kg and cross-sectional area 
is floating vertically in a liquid. The block is depressed slightly and then released. It is observed to execute simple harmonic motion. What is the frequency of these oscillations? (Take the density of the liquid, 
, 
and 
)
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
The buoyant force on the submerged part of the block is
Density of the liquid, 
Acceleration due to gravity, 
Cross-sectional area, 
Therefore,
The angular frequency of SHM is given by 
Therefore, 
.
