In the form of Millikan's experiment, an oil drop was observed to fall with a const
velocity of 2.5 x 10*ms in the absence of an electric field. When a p. d of 1000V
applied between the plates 10mm apart, the drop remained stationary betwe
them. If the density of oil is 9 x 10²kgm", density of air is 1.2kgm and viscosity
air is 1.8 × 10-Nsm-. Calculate the radius of the oil drop and the number of elec
charges it carries.
