A spherical liquid drop is placed on a horizontal plane . A small distrubance cause the volume of the drop to oscillate . The time period oscillation (T) of the liquid drop depends on radius (r) of the drop , density `(rho)` and surface tension tension (S) of the liquid. Which amount the following will be be a possible expression for T (where k is a dimensionless constant)?

Options

A. `ksqrt((rhor)/S)`
B. `ksqrt((rho^2r)/S)`
C. `ksqrt((rhor^3)/S)`
D. `ksqrt((rhor^3)/S^2)`

Answer

C
