Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

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 the above

Explanation:

Detailed explanation-1: -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.

Detailed explanation-2: -When a conducting sphere is charged positively, initially the charge is deposited on the left side. However, due to the sphere’s conducting nature, the charge spreads uniformly throughout the surface of the sphere. Charge is uniformly distributed because: excess electrons within the sphere move toward excess protons.

Detailed explanation-3: -A positively charged rod is brought near one of them, attracting negative charge to that side, leaving the other sphere positively charged. This is an example of induced polarization of neutral objects. Polarization is the separation of charges in an object that remains neutral.

Detailed explanation-4: -The electric field of a conducting sphere with charge Q can be obtained by a straightforward application of Gauss’ law. Considering a Gaussian surface in the form of a sphere at radius r > R, the electric field has the same magnitude at every point of the surface and is directed outward.

Detailed explanation-5: -If point P is placed inside the solid conducting sphere then electric field intensity will be zero at that point because the charge is distributed uniformly on the surface of the solid sphere so there will not be any charge on the Gaussian surface and electric flux will be zero inside the solid sphere. i.e.
