Question

15. In Millikan's oil drop method, the condenser plates
are 8 x 10-3 m apart, the radius of the droplets
2.8 x 10-ºm, and the density of oil is 920 kg m-3, 117
single excess electron is attached to the droplet, whe
would be potential difference between the condense
plates in order to counter balance the weight of the
droplet?
