JEE Main 2022 — Mechanical Properties of Fluids Question with Solution

JEE Main 2022 (27 Jun Shift 1)

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, then the viscous force acting on the ball, will be

Choose an option

Show full solutionCorrect option: B
Correct answer
Bmg1-d2d1

Step-by-step explanation

At the time of terminal velocity ball is in equilibrium i.e. Fg=Fb+Fv

⇒Fv=Fg-Fb

⇒Fv=mg-d2md1g

⇒mg1-d2d1
