The velocity of a small ball of mass M and density d when dropped in a container filled with glycerine becomes constant after some time. If the density of glycerine is 
, then the viscous force acting on the ball will be [NEET 2021]
A
B
C
D
2 Mg
Text Solution
Verified by ExpertsThe correct answer is:
A
As we know that,
Viscous force 
weight - buoyant force
Viscous force 
Here, 
is the volume of submerged bodies,
is the density of the small ball,
is the density of the glycerine,
Substituting the given values in the viscous force expression, we get
Viscous force 
Viscous force
