Why is the electric field inside a conductor zero even though it contains charges on its surface?

Force due to two charges on a charge at center is equal and opposite. Hence intensities are also opposite. This is applicable to each charge on surface of sphere. Therefore total intensity at center or inside a charged conductor is zero.

Is there charge inside a conducting sphere?

Gauss’ law tells us that the electric field inside the sphere is zero, and the electric field outside the sphere is the same as the field from a point charge with a net charge of Q. This result is true for a solid or hollow sphere. So we can say: The electric field is zero inside a conducting sphere.

What is the electric potential inside a conductor?

Since an electric field requires the presence of a charge, the electric field inside the conductor will be zero i.e., E=0 . Thus the electric potential will be constant inside the conductor. So the correct option is C.

Why potential is not zero inside the sphere?

Since all the charge is distributed on the surface of the spherical shell so according to Gauss law there will not be any electric flux inside the spherical shell, because the charge enclosed by the spherical shell is zero, so there will not be any electric field present inside the spherical shell.

Why is electric potential constant inside a conductor?

As inside the conductor the electric field is zero, so no work is done against the electric field to bring a charge particle from one point to another. Because there is no potential difference between any two points inside the conductor, the electrostatic potential is constant throughout the volume of the conductor.

Is potential zero inside a conductor?

The electric field inside a conductor is always zero. So due to which electric potential difference is too zero. In this case total electric potential is zero as net charge inside the conductor is zero. No change in net charge of conductor due to outside charge.

When a charged conductor is placed in an external electric field inside the conductor we have?

When a conductor is placed in an external electrostatic field, the net electric field inside the conductor becomes zero after a small instant of time.

When a conductor is placed in an electric field the field inside the conductor is?

zero
When conductors are placed in an electric field, their electrons are moved. Electrons in a conductor move in the opposite direction when placed in an electric field. Inside the conductor, now there are actually 2 equally balanced opposite Electric Fields. So, the net field inside the conductor is zero.

What is the potential energy of a conductor with no charges?

The lowest potential energy for a charge configuration inside a conductor is always the one where the charge is uniformly distributed over its surface. This is why we can assume that there are no charges inside a conducting sphere. Also, the electric field inside a conductor is zero.

Why is the net charge inside a conductor zero?

If there was a net electric field inside, the charges would rearrange because of it, and cancel it out.) Using Gauss’ law on a spherical surface that has the same center as your conductor, (but a radius that is smaller by an infinitesimal amount) you can conclude that the net charge inside the conductor is zero.

Do the charges move inside a conductor?

Now if there’s any E → inside the conductor , we can surely say then the charges must move . But we are assuming there is electrostatic condition , means no charges are moving .

What is the charge on the inside of a hollow conductor?

No charge on the inside surface of a hollow charged conductor. The electric conductors used in the experiments we have described are generally made of hollow brass or else of wood covered with tinfoil. No advantage is to be gained by making them of solid metal, since the charge resides only on the outside surface.
