Is the electric field inside an insulating sphere zero?

It is zero. You know the electric field of an insulating sphere having charge “q” distributed uniformly has a formula for electric field.

Why is the electric field inside an insulator not zero?

This is attributed to the fact that the electrons are loosely bound to the nuclei and they are free to rearrange themselves until the net field becomes zero. But in an insulator the electrons are tightly bound to the nuclei. So they can resist movement even at more intense fields. So net field is not zero.

Is there electric field inside an insulator?

We define a conductor as a material in which charges are free to move over macroscopic distances—i.e., they can leave their nuclei and move around the material. An insulator is anything else. … There can be no electric field inside a conductor. If there were, it would exert a force on the charges causing them to move.

What is the electric field inside a hollow insulating sphere?

The electric field inside a hollow charged insulating sphere is zero.

Why is field strength zero inside a sphere?

It is because charge doesn’t reside inside it, it moves outside the surface of it producing electric field inside zero. Because at any point inside the spherical shell the total charge enclosed is zero.

Why is there no electric field inside the hollow electrode?

From Gauss law, the electric field is zero inside the hollow conducting sphere. So, the electric field inside any hollow conducting surface is zero provided that there are no charges enclosed by that region. In electrostatics free charges in a good conductor reside only on the surface.

What is the magnitude of the electric field outside of the insulating slab?

The magnitude of the electric field outside the slab is expressed as Eout = dρ/2ε.
