An oil drop carrying a charge of 3e falls under gravity with a constant velocity of 4.6x10 m/s between two metal plates 5mm apart. When a p. d of 4600V is applied to the plates, the drop rises steadily. Calculate; (1) Radius of oil drop (2) Velocity with which the oil drop rises [density of oll 900kgm viscosity of air 18x10 "Nim] assume the effect of air buoyancy is negligible
