# Quick Answer: How could you use Gauss’s law to determine the electric field?

Contents

Using the equations for the flux and enclosed charge in Gauss’s law, we can immediately determine the electric field at a point at height z from a uniformly charged plane in the xy-plane: →Ep=σ02ϵ0ˆn.

## Can we use Gauss law to find out the electric field due to any charge distribution?

We can now determine the electric flux through an arbitrary closed surface due to an arbitrary charge distribution. … We can use this electric field to find the flux through the spherical surface of radius r, as shown in (Figure). A closed spherical surface surrounding a point charge q.

## What is the formula for finding electric field?

the magnitude of the electric field (E) produced by a point charge with a charge of magnitude Q, at a point a distance r away from the point charge, is given by the equation E = kQ/r2, where k is a constant with a value of 8.99 x 109 N m2/C2.

## 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.

## What is Gauss’s law and its application?

The law relates the flux through any closed surface and the net charge enclosed within the surface. The law states that the total flux of the electric field E over any closed surface is equal to 1/?o times the net charge enclosed by the 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. Therefore, The given answer is correct.

## What is electric field due to a line charge on wire?

An electric field is defined as the electric force per unit charge. It is given as: E = F/Q.

## What is the electric field due to an infinite sheet of charge?

Since, E is always constant. Where σ is the charge density and A is the area. ∴ Electric field due to an infinite conducting sheet of the same surface density of charge is E2.

## What is Poisson’s equation in free space?

Explanation: The Poisson equation is given by Del2(V) = -ρ/ε. In free space, the charges will be zero. Thus the equation becomes, Del2(V) = 0, which is the Laplace equation.
