    see the attachment,by dividing the q obtained with charge of an electron,you will get the no of electrons.ie n=(8×10^-19)/(1.6×10-19)=5 And for solving such problems,you should have a good knowledge of terminal velocity and viscosity problems in classical mechanics. And a little bit knowledge of Millikan's oil drop experiment is also required in this question.
