Two identical metal spheres A and B are supported on insulating stands and placed in contact. What kind of charges will A and B develop when a negatively charged ebonite rod is brought near A? (A) A will have a positive charge and B will have a negative charge (B) A will have a negative charge and B will have a positive charge (C) Both A and B will have positive charges (D) Both A and B will have negative charges

In contact, A and B behave as one body. Therefore, by induction, positive charge developes on A and negative charge developes on farther side of B.

Q. Two identical metal spheres A and B are supported on insulating stands and placed in contact. What kind of charges will A and B develop when a negatively charged ebonite rod is brought near A?

A will have a positive charge and B will have a negative charge

A will have a negative charge and B will have a positive charge

Both A and B will have positive charges

Both A and B will have negative charges

In contact, A and B behave as one body. Therefore, by induction, positive charge developes on A and negative charge developes on farther side of B.
