Solution

Earthing serves as a seemingly infinite reservoir of electrons. It is capable of transferring electrons to or receiving electrons from a charged object in order to neutralise that object. According to question, when a positively charged rod is brought near a neutral sphere which is earthed as well, then the grounded sphere is capable of transferring electron near the positively charged rod.

Q. Two neutral conducting spheres are next to each other and touching each other, They are also each separated from the table with an insulating stand. Then, a negatively charged rod is brought near, but not touching, sphere A. The two spheres are then separated by touching only their insulating base. Finally, the charged rod is removed. What are the charges of sphere A and sphere B?
