A spherical liquid drop is placed on a horizontal plane. A small distance causes the volume of the drop to oscillate. The time period of oscillation (T) of the liquid drop depends on radius (r) of the drop, density ($$\rho $$) and surface tension (S) of th liquid. Which among the following will be a possible expression for T (where, k is a dimensionless constant)?
A
$$k\sqrt {{{\rho r} \over S}} $$
B
$$k\sqrt {{{{\rho ^2}r} \over S}} $$
C
$$k\sqrt {{{\rho {r^3}} \over S}} $$
D
$$k\sqrt {{{\rho {r^3}} \over {{S^2}}}} $$
