Solution

The correct option is A earth to sphere
Due to induction, side $A$ will have excess electrons as electrons get shifted towards the positive charge carrier.
Therefore, side $B$ have deficient in electrons.

When connected to earth, electrons will flow from earth to sphere.
Hence, option $(a)$ is correct.

While charging a metallic sphere negatively by induction by bringing a positively charged rod near it the electrons will flow from the ground to the sphere when the sphere is connected to the ground with a wire. WHY DOES THIS HAPPEN?

Q. A positively charged rod is brought near to a neutral spherical conductor. After that, the sphere is grounded. The final charge on the sphere, after disconnecting earthing wire will be

Q. Consider a neutral conducting sphere. A positive point charge is placed outside the sphere. Then the net charge on the sphere will be
