Answer» Solution :Electerical force is blanced by the weight of the MASS ` mg = qEE = elecrtric field ` or `mg= q. V.C / eplision _0 A` (:. Eplision_0 A / d = C :. 1 / d = C / eplision_0 A)` V = mg eplision_0 A / q.C ` `= 10^(-6) xx 9.8 xx 8.88 xx 10^(-12) xx 100 xx 10^(-4) / 10 xx 10^(-8) xx 0.04 xx 10^(-6)` `V = 43 m V`. |
