Question

How can you charge a metal sphere positively by induction process

Answer 1

Answer:

1. Bring the neutral metal sphere near a negatively charged sphere.
2. The surface of metal which is nearer to -ve charged sphere will get accumulated with +ve charge where as the other side of sphere will accquire -ve charge.
3. Now join a earth connected wire to the sphere on the side with - ve charge.
4. The Earth will take extra electrons from the sphere i.e, take -ve charge and thus eventually due to lack of electrons the side with -ve charge will also become + ve.
