1. A flat air condenser, the distance between the plates of which is 2 cm, is charged up to a potential difference of 3000 V. What will be the field strength of the capacitor if, without disconnecting it from the voltage source, the plates are extended to a distance of 5 cm? Calculate the energy of the capacitor before and after the separation of the plates. The area of each plate is 100 cm2.
