# What is electric field inside a solid conducting sphere?

Contents

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.

## Why electric field inside a conducting solid sphere is zero?

If point P is placed inside the solid conducting sphere then electric field intensity will be zero at that point because the charge is distributed uniformly on the surface of the solid sphere so there will not be any charge on the Gaussian surface and electric flux will be zero inside the solid sphere. i.e.

## How do you find the electric field of a solid sphere?

The electric field of a sphere of uniform charge density and total charge charge Q can be obtained by applying Gauss’ law. Considering a Gaussian surface in the form of a sphere at radius r > R, the electric field has the same magnitude at every point of the surface and is directed outward.

## What is the electric field inside a conducting shell?

* The electric field inside the conducting shell is zero. (B) There can be no net charge inside the conductor, therefore the inner surface of the shell must carry a net charge of -Q1, and the outer surface must carry the charge +Q1 + Q2, so that the net charge on the shell equals Q2.

## Is electric field zero inside a sphere?

The electric field is zero inside a conducting sphere. The electric field outside the sphere is given by: E = kQ/r2, just like a point charge. The excess charge is located on the outside of the sphere.

## Is electric field inside a solid sphere is zero?

Yes it is zero according to Gauss Law. 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.

## Is there an 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.

## Which is not deflected by electric field?

Alpha particles are positively charged as they have two protons and two neutrons. … This means that alpha and beta radiation can be deflected by electric fields, but gamma radiation cannot. Hence the types of waves that cannot be deflected by an electric field or a magnetic field are gamma rays.

## Can electric field be negative?

Electric field is not negative. It is a vector and thus has negative and positive directions. An electron being negatively charged experiences a force against the direction of the field. For a positive charge, the force is along the field.

## Is the electric field inside a conductor zero?

The net electric field inside a conductor is always zero. So, there is no electric field lines inside a conductor. … In conductor , electrons of the outermost shell of atoms can move freely through the conductor. These electrons are called free electrons.

## What is electric field unit?

The units of the electric field in the SI system are newtons per coulomb (N/C), or volts per meter (V/m); in terms of the SI base units they are kg⋅m⋅s3⋅A1.

## What is electric field formula?

Electric field can be considered as an electric property associated with each point in the space where a charge is present in any form. An electric field is also described as the electric force per unit charge. The formula of electric field is given as; E = F /Q.

## Why there is no charge inside a sphere?

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.
