Properties Of Matter

A small spherical ball of radius 0.1 mm and density 10⁴ kg m^\(-\)3 falls freely under gravity through 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 \(\times\) 10^\(-\)5 N-sm^\(-\)2).
