MHT CET Physics question
The velocity of a small ball of mass 'M' and density 'd₁' when dropped in a container filled with glycerine becomes constant after some time. If the density of glycerine is 'd₂', the viscous force acting on the ball is (g = acceleration due to gravity) [MHT-CET 2021]
Answer: (D)
Solution
At constant velocity weight = upthrust + viscous force, with upthrust , so \frac{Mgd_2}{d_1}$ =
