## Why is excess charge on the surface of a conductor?

The electric field will cause the charges to move, and they will do so until this electric field is zero. Gauss’s law then also tells us that this will be accomplished once there is no net free charge within the conductor, so the free charge must accumulate on the surface.

## Where is the excess charge distributed on each shell?

Excess charges are always on the surface of the conductors. A spherical conducting shell has an excess charge of +10 C. A point charge of −15 C is located at center of the sphere.

## Does a conductor have excess electrons?

Electrons, like human beings, wish to manipulate their surroundings in an effort to reduce repulsive effects. Since these excess electrons are present in a conductor, there is little hindrance to their ability to migrate to other parts of the object. And that is exactly what they do.

## What is meant by excess charge?

Excess Charges means the amount of Billed Charges less Non-Covered Charges, in excess of the Covered Charges determined by MMO for a Non-Contracting Institutional Provider. … Excess Charges means the difference between Billed Charges and the applicable Allowed Amount or Non-Contracting Amount.

## Does a conducting shell have charge?

* 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.

## What is the charge inside a conductor?

The inside of the conductor does not contain any charge. If charges were present inside a conductor then such charges would produce an electric field and the electrons would move and cancel out the field neutralizing the charge. Charges, therefore, must reside on the surface.

## Where do electric field lines start and end?

Electric field lines begin on positive charges and end on negative charges, or at infinity. The number of lines entering or leaving a charge is proportional to the magnitude of the charge.

## What is the total charge on the conducting sphere?

zero
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 is there no charge inside a conducting 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.

## What is the charge on the outer surface of the conductor?

What is the charge on the outer surface of the conductor? A charge inside a cavity of a metal. Charges at the outer surface do not depend on how the charges are distributed at the inner surface since E field inside the body of the metal is zero.

## Where is the charge on a conducting metal sphere present?

Answer: Correct option is a) On the surface of sphere.

## Why is the charge inside a conductor zero?

Electric field is zero inside a charged conductor. For a charged conductor, the charges will lie on the surface of the conductor.So, there will not be any charges inside the conductor. When there is no charge there will not be electric field.

## What is a conducting sphere?

A conducting hollow sphere will have the entire charge on its outer surface and the electric field intensity inside the conducting sphere will be zero. For a spherical charged Shell the entire charge will reside on outer surface and again there will be no field anywhere inside it.

## Can solid sphere be conducting?

A solid conducting sphere, having a charge Q, is surrounded by an uncharged conducting hollow spherical shell. Let the potential difference between the surface of the solid sphere and that of the outer surface of the hollow shell be V.

## When electric charge is given to a metallic sphere then all charge is?

zero
Hint: When the charge is given to the metallic sphere, the electric field inside the sphere will be definitely zero in all conditions.

## Can a solid sphere be a conductor?

A solid conducting sphere holds more charge than a hollow sphere of the same radius when they are at same potential. A solid conducting sphere hold more charge than a hollow sphere of same radius.

## Can flux be negative?

The negative flux just equals in magnitude the positive flux, so that the net, or total, electric flux is zero. If a net charge is contained inside a closed surface, the total flux through the surface is proportional to the enclosed charge, positive if it is positive, negative if it is negative.

## What is non conducting sphere?

Non conducting sphere : For a NON CONDUCTING charged SPHERE the there will be a electric field outside as well as inside. Inside at a point it will be proportional linearly to the the distance of that point from the centre of sphere .

## Can a conducting solid sphere hold charge at its centre?

Nill . There is no charge in the centre of an sphere . Charges are present only at the surface of any object .

## Is an electric field always positive?

So even in case if charge is negative , then due to mod it becomes positive . Hence Electric Field also becomes positive . So , electric field is always positive .

## What is meant by Gauss law?

or Gauss’ law, Gauss’s law

noun Physics. the principle that the total electric flux of a closed surface in an electric field is equal to 4π times the electric charge inside the surface.

## Is flux scalar or vector?

scalar quantity
Electric flux is a scalar quantity because it is the dot product of two vector quantities, the electric field, and the perpendicular differential area.
