Question

A spherical ball of radius 3 x 10 mand density
104 kg/m3 falls freely under gravity through a
distance h before entering a tank of water. If after
entering the water the velocity of the ball does
not change, then value of his
(Viscocity of water is 10-5N-s/m2)​

Answer 1

Answer:

Before entering the water the velocity of ball is √2gh . If after entering the water this velocity does not change then this value should be equal to the terminal velocity.
