Answer:
Since the ball attains equilibrium when the velocity becomes constant.
The effective force of the liquid must balance the viscous force
Effective force =V(d1−d2)g=V(d1−d2)g
But v=Md1v=Md1
∴∴ effective viscous force =Md1=Md1(d1−d2)g(d1−d2)g
=Mg(1−d2d1)=Mg(1−d2d1)
Hence a is the correct answer.
