Why potential inside charged spherical shell is constant?

There is no volume charge inside the sphere, hence no more change in the potential . ie constant.. only the charge on the surface contribute to the inside potential and this does not change with r.

Which of the following quantities do not depend on the choice of zero potential or zero potential energy?

Option (d) is correct as the change in potential energy of the two-charge system is independent of our choice of the zero-potential point. Thus, we conclude that potential difference between two points and change in potential energy of a two-charge system don’t depend on the choice of zero potential point.

Why is the electric potential not zero?

At the midpoint between the charges, the electric field due to the charges is zero, but the electric potential due to the charges at that same point is non-zero.

Why is the potential inside a spherical shell zero?

The inner surface of the conductor is smaller than the upper one. So all the charges are coagulated on upper surface to minimize the repulsion force. That’s why there is no charge inside the spherical conductor and thus no potential.

Which does not depend on zero potential?

Normally infinity is taken as reference point where potential is assumed to be zero. If choice of zero potential is changed, then the potential at a point will also change. Option (b) is correct as difference in potential between the two points doesn’t depend on the choice of zero potential.

Which of the following qualities do not depend on the choice of zero potential?

Potential and potential energy depend on the choice of a reference point of zero potential or zero potential energy. But the difference of potential and energy does not depend on the choice of the reference point. Hence, the correct options are (b) and (d).

Why should electrostatic field be zero inside a conductor?

Electric field is zero inside a charged conductor. For a charged conductor, the charges will lie on the surface of the conductor.So, there will not be any charges inside the conductor. When there is no charge there will not be electric field.

Why is the electric field zero for conducting spherical shell?

Its zero for conducting spherical shell because the entire bulk of the shell forms an equipotential surface in all direction (call it an equipotential volume) and as the electric field is the negative gradient of potential, it turns out to be zero inside the equipotential volume. So, no charges remain inside the shell and all appear on the surface.

What is the potential potential inside a hollow charged spherical shell?

Potential inside a hollow charged spherical shell. The book says that a hollow charged sphere has an equal potential at all points on and inside the sphere but the points inside the sphere have zero net electric field for they have no charge.

Why is the potential inside the shell non zero?

Therefore, integral of field from R to any point inside the shell will be zero. So, work done up to any point inside the shell is the same as that equal to work done upto surface of the shell. So, potential at any point inside the shell is equal to the potential on the surface of the shell. Thus, within the shell potential is non zero.

Why is the charge differential of a charged sphere zero?

Because the shell is charged and it must be conductive to satisfy the claim that it is “uniformly charged”. Therefore the conductive shell is at the same potential at all points and there is no charge differential to create an electric field with the shell. Well, its zero only if the sphere is a good conductor of electricity.
