In an experiment to verify Stokes law , a small spherical ball of radius r and density `rho` falls under gracvity throught a distance h in air before entering a tank of wate . If the terminal velocity of the ball inside water is same as its velocity just befor entering the water surface , then the value of h is proportional to : ( ignore viscosity of air ) .
