Can somebody explain me the milikan's oild drop experiment? I am extremely confused that how milikan's oil drop experiments works? Specially for
U + Fv = W on the effect of gravity, if
U + Fv = W then, why is the oil drop falling. Should it be stopped in the air because both forces are equal i,e Downward Force = Upward ?
U = Upthrust
Fv = Viscous Force
W = Weight of oil drop
