### Question

A liquid drop placed on a horizontal plane has a near spherical shape (slightly flattened due to gravity). Let R be the radius of its largest horizontal section. A small disturbance causes the drop to vibrate with frequency ν about its equilibrium shape. By dimensional analysis the ratio can be (here σ is surface tension, ρ is density, g is acceleration due to gravity, and k is an arbitrary dimensionless constant)
