A charged oil drop of mass `2.5xx10^(-7)`kg is in space between the two plates, each of area `2xx10^(-2) m^(2)` of a parallel plate capacitor. When the upper plate has a charge of `5 xx10^(-7) C` and the lower plate has an equal negative charge, then the oil remains stationary. the charge of the oil drop is (take, `g=10 m//s^(2)`)
