Answer» When a small sphere moves at low speed through a fluid, the viscous force $F$ , opposing the motion is experimentally found to depend upon the radius $r$ , the velocity $v$ of the sphere and the viscosity $η$ of the fluid. Expression of force is proportional to Hint: $[η] = [M L^{- 1} T^{- 1}]$
