Two plane parallel conducting plates `1.5xx10^(-2)m` apart are held horizontal one above the other in air. The upper plate is maintained at a positive potential of`1.5kV` while the other plate is earthed. Calculate the number of electrons which must be attached to a small oil drop of mass `4.8xx10^(-15)kg` between the plates of move the drop with constant speed. Neglect the density and viscosity of air.
