Use conservation of energy

change in potential energy(qV )= change in kinetic energy

(-2C)(10V) = -20J

KE decreases by 20J

When work done is positive, KE increases. When work done is negative, KE decreases.

A parallel-plate capacitor has a plate area of 100c * m ^ 2 and a plate separation of 2.0 cm. has been charged up to 3000 V by a battery. Now, (i) after disconnecting the battery, (ii) keeping the battery connected, the distance between the plates is increased to 5.0 cm intensity of electric field between the plates and the energy of the capacitor. ( epsilon_{0} = 8.85 * 10 ^ - 12 * F * m ^ - 1
