A small spherical ball of radius 0.1 mm and density 10⁴ kg m⁻³ falls freely under gravity through a a distance h before entering a tank of water. If after entering the water the velocity of ball does not change and it continue to fall with same constant velocity inside water, then the value of h will be____m. (Given g = 10 ms⁻², viscosity of water = 1.0 × 10⁻⁵ N-ms⁻²).
