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 \(\dfrac{d}{2}\) then the viscous force acting on the ball will be:
1. \(\dfrac{3Mg}{2}\)
2. \(2Mg\)
3. \(\dfrac{Mg}{2}\)
4. \(Mg\)

A viscous liquid flows slowly through a pipe of cross-sectional radius \(R.\) The speed of the particles is a function of the distance from the axis of the pipe.
Assume that the flow is smooth. The variation of \(v\) vs \(r\) is best given by the graph:
