The downward velocity of a small metal ball of mass 
and density 
becomes constant finally, when dropped in a container filled with glycerine. If the density of glycerine is 
, the viscous force acting on ball after long time is:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
Since, ball gains constant velocity
Therefore, net force on the ball = zero
Weight of the ball 
Buoyant force + Viscous force
