Question

In one experiment a singly charged drop was found to fall under gravity at terminal velocity of 0.0040cm per second and rise at 0.01200cm per second when a field of 2×10^5 volt per metre was suitably applied. Calculate electronic charge . Given that radius= 6×10^-7, viscosity =1.81×10^-5Ns per metre square
