Two spheres A and B made of same material of masses m and 8m respectively are dropped into a long viscous liquid column. If F_(A) and F_(B) are viscous liquid column. If F_(A) and F_(B) are viscous force on A and B respectively when they attained their terminal velocity find F_(A):F_(B)

If V is Velocity of oil drop , than according to stok's law, the viscous drag force on an oil drop is proportional to

A thin plate of large area is placed midway in a gap of height h filled with oil of viscosity and the plate is pulled at constant velocity v by applying the same drag force on the plate. If a lighter oil of viscosity eta is then substituted in the gap. it is found that for the velocity v , and the same drag force as previous case the plate is located unsymmetrically in the gap but parallel to the walls. Find eta in terms of distance from nearer wall to the plane y .

A small spherical ball falling through a viscous medium of negligible density has terminal velocity v. Another ball of the same mass but of radius twice that of the earlier falling through the same viscous medium will have terminal velocity
