A spherical ball of radius $1\times 10^{-4}\mathrm{m}$ and density $10^5\mathrm{kg}/{\mathrm{m}}^3$ falls freely under gravity through a distance $h$ before entering a tank of water, If after entering in water the velocity of the ball does not change, then the value of $h$ is approximately: (The coefficient of viscosity of water is $9.8\times 10^{-6}\mathrm{N}\mathrm{s}/{\mathrm{m}}^2$ )
