A metallic sphere of radius 1.0 × 10^−3 m and density 1.0 × 10^4 kg/m^3 enters a tank of water, after a free fall through a distance of h in the earth’s gravitational field. If its velocity remains unchanged after entering water, determine the value of h. Given: coefficient of viscosity of water = 1.0 × 10^−3 Ns/m^2,g = 10 m/s^2 and density of water =1.0× 10^3 kg/m3.
