If the time period \[(T)\]  of vibration of a liquid drop depends on surface tension \[(S)\], radius \[(r)\]  of the drop and density \[(\rho )\] of the liquid, then the expression of \[T\] is                    [AMU (Med.) 2000]

A.             \[T=k\sqrt{\rho {{r}^{3}}/S}\]
B.             \[T=k\sqrt{{{\rho }^{1/2}}{{r}^{3}}/S}\]
C.             \[T=k\sqrt{\rho {{r}^{3}}/{{S}^{1/2}}}\]          
D.             None of these
Answer» B.             \[T=k\sqrt{{{\rho }^{1/2}}{{r}^{3}}/S}\]
