MHT CET Physics question
A spherical solid ball of volume 'V' is made of a material of density ''. It is falling through a liquid of density . Assume that the liquid applies a viscous force on the ball that is proportional to the square of the speed , i.e. , then the terminal speed of ball is (g = acceleration due to gravity) [MHT-CET 2022]
Answer: (C)
Solution
At terminal speed weight = upthrust + viscous force: , so $ =
