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