You asked: Is electric field inside a cavity zero?

The electric field inside a cavity is only zero if the cavity contains no charges.

Is there electric field inside a cavity?

In a static situation, there can be no field inside a conductor. If there were, charges would move until there was no field. This means that every point within a conductor (including points on the surface of an empty cavity) is at the same potential. This in tern means there can be no field inside the cavity.

Why there is no electric field inside a cavity?

If an isolated conductor without cavities is charged, its excess charge will distribute itself on its surface in order to guarantee that the electric field is zero on its interior.

What is the electric field inside the cavity of a conductor?

Assertion: In a cavity within a conductor, the electric field is zero. Reason: Charges in a conductor reside only at its surface.

What is the electric field in a cavity of metal?

Electric field inside a metallic cavity is zero.

Is the electric field inside a cavity with no charge zero?

Hence electric field intensity inside a cavity with no charge is always zero.

Is the electric field inside a cavity with no charge zero even if the shell is not spherical?

Yes, the electric field inside the cavity is zero even when the shape is irregular and not the sphere.

Why electric field is zero in the cavity of a hollow charged conductor?

This field is basically the superposition of two fields. The field due to cavity and the field due to the rest of the charged conductor. These fields are equal in magnitude and opposite in direction inside the conductor, that is why the net field inside the conductor is zero.

What is electric cavity?

An electromagnetic cavity is a cavity that acts as a container for electromagnetic fields such as photons, in effect containing their wave function inside. The size of the cavity determines the maximum photon wavelength that can be trapped.

Is the potential in the cavity of a charged conductor zero?

Potential inside the cavity is not zero. Potential is constant.

What is the electric field in the cavity if a conductor of the electric field having a cavity is charged does the result depend on the shape and size of cavity of the conductor?

This phenomenon is called electrostatic shielding. Hence net electric field is zero inside the cavity in a conductor, irrespective of shape, size or location of the cavity.

What is the electric field in the cavity if a conductor having a cavity is charged?

Answer: The Electric field inside a hollow spherical conductor is zero. The reason being simple that according to the Gauss’ law the electric Flux depends on the charges enclosed inside a Gaussian surface.
