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/(sqrt(5)) meter, the attractive force between the plates balances the pulley block system. Then find value of V_(0) in volts (EMF of battery). (Take area of the plate =20/(3epsilon_(0))m^(2) )
