200 Fair capacitor is connected to a power supply, the energy stored in the capacitor is 900 x 10% ]. While the capacitor is kept connected to the power supply, a slab of dielectric is inserted that completely fills the space bere the plates. This increases the stored energy by 180 x 10-5 J. What is the potential difference between the capacitor plates after the dielectrie is inserted?
