Why is electric field zero inside a charged sphere?

When a spherical shell is charged, the charges get distributed uniformly over its outer surface and the charge inside the shell is zero. According to Gauss’s law, as the charge inside is zero, the electric flux at any point inside the shell will be zero.

Is there charge inside a sphere?

Charge Q is uniformly distributed throughout a sphere of radius a. That is, the electric field inside the sphere of uniform charge is zero at the center and increases linearlywith radius r: Of course, the two expressions for the electric field match — have the same value — at the surface of the sphere, for r = a.

What is the electric field inside a spherical shell?

All charge resides on the outer surface so that according to Gauss law, electric field inside a shell is zero. A spherical conducting shell of inner radius r1 and outer radius r2 has a charge Q.

Is electric field zero inside a 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 charge inside a hollow sphere?

The correct answer is A. Consider a hollow conducting sphere of radius R. Since charge enclosed within the gaussian surface is zero.

Why is there no charge inside a hollow conductor?

Electric charge given to any hollow conductors reside on the outer surface. No charge can exist inside the conductor on account of electric shielding effect. This motion of charges forces them to move to the outer surfaces of the conductor. Thus, any charge given to a hollow conductor remains on its outer surfaces.

Is there electric field inside a hollow conductor?

It is well known that no electric fields exist inside a hollow conductor, even if there are charges present outside. A charge inside a hollow conductor produces a charge distribution on the outer surface of the conductor, and this induced charge distribution creates an electric field outside the closed conductor.

Why is there no net electric field in a spherical shell?

If the charges on the spherical shell are uniformly distributed, then there will be no net electric field due to the shell anywhere within the shell.

What is the magnitude of electric field inside a charged spherical shell?

It would experience no net force inside shell. It is free to move. Since there are no charges inside a charged spherical shell . This means the net charge is equal to zero. So magnitude of electric field E =0. So there is no net force. So magnitude of net force =0.

Why are there no charges inside a conducting sphere?

This is why we can assume that there are no charges inside a conducting sphere. Also, the electric field inside a conductor is zero. Therefore, all the charge has to lie on the surface of the conductor. (As this is the only part of the conductor outside your Gaussian surface.)

Is the electric field inside a spherical conductor zero?

The electric field of inside of a spherical conductor is zero the charge is distributed evenly. around the surface of the conductor. is the electric field inside a cavity zero even if the shell is not spherical? The electric field intensity inside a cavity is zero, even if the shell is not spherical and has any irregular shape.
