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 for $T$ is:

  • 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
