If the time period (T) of vibration of a liquid drop depends on surface tension (S), radius (r) of the drop and density 
of the liquid, then the expression of T is
A
B
C
D
None of these
Text Solution
Verified by ExpertsThe correct answer is:
A
Let 
or T = 
By substituting the dimension of each quantity in both sides
By equating the power of M , L and T in both sides 
, 
, 
By solving above three equations 
, 
, 
So the time period can be given as,
.
