CBSE Class 12-science Answered

can two surface with equal potential intersect?
Asked by jithin | 25 Dec, 2015, 05:53: PM
answered-by-expert Expert Answer
No, two equipotential surfaces can never intersect. An equipotential surface is normal to the electric field. At the point of intersection, there will be two directions of electric field, which is impossible.

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
