A spherical ball of density p and radius R is floating in completely submerged condition in a liquid of density \[\rho \] and surface tension T. When a cavity of radius \[\frac{5R}{6}\] is created within the ball, the ball now floats half submerged in liquid. Then value of \[\frac{T}{{{R}^{2}}}\] is given by \[(\rho =1\,kg/{{m}^{3}})\]:
