FAQ

Those who are looking for an answer to the question «Why there is an electric field inside a non-conducting sphere based?» often ask the following questions:

👉 Can an electric field exist inside a conducting sphere?

The reason is, in case of conducting sphere electric field do not penetrate inside the sphere so there is no variation of electric field inside a conducting sphere, so work done in moving an object in a closed path is zero inside a conducting sphere and that's why electric potential

👉 The electric field inside a hollow conducting sphere will?

If you have a conducting hollow sphere with a uniform charge on its surface, then will the electric field at every point inside the shell be 0. The reason the electric field is 0 at the center is clear from the symmetry of the sphere, but for a point at a certain distance from the center, shouldn't a net electric field exist?

👉 What is the electric field inside a conducting sphere?

What is the electric field inside a sphere? The electric field inside a sphere of uniform charge is radially outward (by symmetry), but a spherical Gaussian surface would enclose less than the total charge Q. The charge inside a radius r is given by the ratio of the volumes: The electric flux is then given by. and the electric field is.

This result is true for a solid or hollow sphere. So we can say: The electric field is zero inside a conducting sphere. The electric field outside the sphere is given by: E = kQ/r 2, just like a point charge. The excess charge is located on the outside of the sphere. In the simulation you can use the buttons to show or hide the charge distribution.

$\begingroup$ You can derive the expression by considering the sphere to have a positive charge density and the cavity to have a negative charge density of equal magnitude. Say you want to find it at a point P inside the cavity. Assume the centre of sphere as origin. Let the position vector of P be r1, the vector joining centre of cavity to P be r2 and position vector of centre of cavity be d.

The use of Gauss’s law to examine the electric field outside and inside of a charged conducting sphere sometimes does not convince students that there is no electric charge or field inside the sphere. This demonstration is designed to show students that this is the case. Materials: Van de Graaff generator with discharge rod

Therefore, the electric field points towards the center.” “Electric field inside a conductor should be zero.“ Careful: what does inside mean? This is always true for a solid conductor (within the material of the conductor) Here we have a charge “inside” A positively charged solid conducting sphere is contained within a

An electric charge is uniformly distributed throughout a non-conducting solid sphere of radius . Determine the electric field everywhere inside and outside the sphere. +Q a Solution: Step 1: The charge distribution is spherically symmetric. Step 2: Since +Q is uniformly distributed throughout the volume, the electric field E G must be radially ...

The electric field inside the conducting shell is zero. There can be no net charge inside the conductor Using Gauss’ Law it can be shown that the inner surface of the shell must carry a net charge of -Q 1 The outer surface must carry the charge +Q1 + Q2, so that the net charge on the shell equals Q2

1) Suppose you put a neutral ideal conducting solid sphere in a region of space in which there is, initially, a uniform electric field. Describe (as specifically as possible) the electric field inside the conductor and the electric field at the surface of the conductor. Describe the distribution of charge in and on the conductor.

If you have a solid conducting sphere (e.g., a metal ball) that has a net charge Q on it, you know all the excess charge lies on the outside of the sphere. 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.

Is electric field zero inside a sphere?

It isn’t necessarily zero. You are probably talking about a uniformly charged sphere with no other external electric fields. In this case, yes, the electric field at the center is zero. If the sphere had a nonuniform charge and/or there was another external electric field, the field at the center would not be zero.

Why is electric field inside a cavity of a non-conducting sphere not zero?

Consider a charged non conducting solid sphere of uniform charge density, and it as hole of some radius at the centre. Now suppose I apply Gauss law. As there is no charge inside the cavity, no charge is enclosed by Gaussian sphere, so electric flux is zero, hence electric field is zero. But this is not true according to sources like this, textbook ...

Why electric field inside a sphere is zero?

Why is electric field zero inside a hollow sphere? Hi, According to Gaussian’s law the electric field inside a charged hollow sphere is Zero. This is because the charges resides on the surface of a charged sphere and not inside it and thus the charge enclosed by the guassian surface is Zero and hence the electric field is also Zero.

Why is electric field inside a sphere zero?

Why is the potential inside a solid conducting sphere non-zero while the electric field inside is zero? The "why" simply goes back to the fundamental laws of electromagnetism (Maxwell's equations), AND to the definition of "electric potential" (i.e., Voltage): the electric field E is the GRADIENT of the Voltage, i.e., the rate of change of Voltage over distance.

Why is electric field zero inside a sphere?

The statement "electric field inside a conductor is zero" is true only after charges have distributed themselves in the most optimal way on the surface - it is an electrostatic result. But if that is so, then the electric field inside the sphere must also be spherically symmetrical. why is the electric field inside a charged sphere zero?

How to find electric field of a charged conducting sphere?

Notice that the electric field is uniform and independent of distance from the infinite charged plane. Electric field of a sphere. Consider a charged spherical shell with a surface charge density σ and radius R. Consider a spherical Gaussian surface with any arbitrary radius r, centered with the spherical shell. By symmetry, the electric field must point radially. Thus, for a Gaussian surface outside the sphere, the angle between electric field and area vector is 0 (cosθ = 1). For a ...
