A capacitance balance is shown in the figure The balance has a block pulley system attached on one side and a capacitor that has a variable gap width on the other side Assume upper plate of the capacitor has negligible mass When the separation between the plate is 1 meter the attractive force between the plates 5 balances the pulley block system Then find value of Vin 20 volts EMF of battery Take area of the plate m 360 10kg 4m 40 3 kg 5kg 4m
