Question

Suppose that a conducting sphere is charged positively by some method. The charge is initially deposited on the left side of the sphere. Yet because the object is conductive, the charge spreads uniformly throughout the surface of the sphere. The uniform distribution of charge is explained by the fact that

• A. the charged atoms at the location of charge move throughout the surface of the sphere
• B. the excess protons move from the location of charge to the rest of the sphere
• C. excess electrons from the rest of the sphere are attracted towards the excess protons
• D. None of these

Answer 1

The correct option is C excess electrons from the rest of the sphere are attracted towards the excess protons

Given a conducting sphere is charged positively. The charge is initially deposited on the left side of the sphere. The charge then spreads uniformly throughout the surface of sphere. This is because negative electrons on left side of sphere are attracted towards the region of positive charge. Therefore, the electrons migrate towards right side of the sphere until there is a uniform distribution of charge.
