## What are the characteristics of Gaussian surface?

Gaussian Surface of a Sphere A point charge. A spherical shell with the uniform charge distribution. Charge distribution with spherical symmetry.

## What is nature of Gaussian surface?

A Gaussian surface is an imaginary closed surface around a charge in a 3 dimensional space. The total amount of flux is calculated by using this surface. Now, the Gaussian surface is an imaginary surface. So it can never be electrical and magnetic in nature.

## What is Gauss law and what is a Gaussian surface?

According to Gauss’s law, the flux of the electric field →E through any closed surface, also called a Gaussian surface, is equal to the net charge enclosed (qenc) divided by the permittivity of free space (ϵ0): 4: The electric flux through any closed surface surrounding a point charge q is given by Gauss’s law.

## What properties must a useful Gaussian surface have?

Essential properties of Gaussian surface: (1) It should be closed surface so that a clear distinction can be made between points that are inside the surface, on the surface and outside the surface. (2) This surface must pass through the point where electric field is to be calculated.

## Can a charge lie on a Gaussian surface?

Gauss’ law does consider charge both inside and outside of the Gaussian surface. It is just that the field lines from charges outside of the Gaussian surface cancel to zero because those field lines both enter and exit the surface. This produces equal flux, but with opposite sign.

## Why charge inside a conductor is zero?

A conductor is a material that has a large number of free electrons available for the passage of current. Hence in order to minimize the repulsion between electrons, the electrons move to the surface of the conductor. Hence we can say that the net charge inside the conductor is zero.

## Is the flux through a closed surface always zero?

The flux of a vector field through a closed surface is always zero if there is no source or sink of the vector field in the volume enclosed by the surface. The flux of a electric field through a closed surface is always zero if there is no net charge in the volume enclosed by the surface.

## What is the importance of Gaussian surface?

Gaussian surface is a closed surface in three dimensional space through which the flux of a vector field is calculated; usually the gravitational field, the electric field, or magnetic field. The concept of Gaussian surface helps in evaluatig the electric field intensity due to symmetric charge distribution.

## What are the applications of Gauss law?

Gauss’s Law can be used to solve complex electrostatic problems involving unique symmetries like cylindrical, spherical or planar symmetry. Gauss’s Law can be used to simplify evaluation of electric field in a simple way.

## What is meant by equipotential surface?

The surface which is the locus of all points which are at the same potential is known as the equipotential surface. In other words, any surface with the same electric potential at every point is termed as an equipotential surface.

## What are advantages of Gauss’s law?

The Gauss theorem is more effectively used in the closed surface for the purpose of finding the electric field and it also effectively work in the charge distribution process as compared to the coulomb’s law.

## What do you mean by electric flux?

Electric flux, property of an electric field that may be thought of as the number of electric lines of force (or electric field lines) that intersect a given area. Electric field lines are considered to originate on positive electric charges and to terminate on negative charges.

## What is an equipotential surface give an example?

a surface all of whose points have the same potential. For example, the surface of a conductor in electrostatics is an equipotential surface. In a force field the lines of force are normal, or perpendicular, to an equipotential surface.

## What is equipotential surface used for?

All points on an equipotential surface have the same electric potential (i.e. the same voltage). The electric force neither helps nor hinders motion of an electric charge along an equipotential surface. Electric field lines are always perpendicular to an equipotential surface.

## What is importance of equipotential surface?

Some important properties of equipotential surfaces : Work done in moving a charge over an equipotential surface is zero. The electric field is always perpendicular to an equipotential surface. The spacing between equipotential surfaces enables us to identify regions of strong and weak fields.

## What is the potential difference between two equipotential surface?

Complete step by step solution The equipotential surface is any surface in which the potential value is constant in any point on that surface. In other terms, the potential difference between any two points in an equipotential surface is equal to zero.

## What does it mean when equipotential is zero?

A charge can freely be moves on an equipotential line or surface. This is because, on an equipotential line or surface ΔV = 0, therefore, W =-q ΔV = 0. It means that the work done by the electric field when a charge moves on an equipotential line/surface is zero.

## Is equipotential surface real or imaginary?

Equipotential Surface A real or imaginary surface in an electric field which has same potential at very point is an equipotential surface or simply, an equipotential. Ex:- A shell having electric charge at its centre, makes an equipotential surface as it has same potential R Q 0 4   at every point of the surface.

## What is the shape of equipotential surface for a point charge?

The shape of the equipotential surface is in the form of concentric spherical shells. There is a decrease in the electric field as we move away from the point charge.
