The correct statement about the variation of viscosity of fluids with an increase in temperature is:

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. \(Mg\)
