Best answer: Why there is an electric field inside a non conducting sphere?

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.

Why is there no field inside a conducting sphere?

To find field inside the hollow sphere we can take take Gaussian surfaces with radii ranging from R=0 to R=r. Any of these surfaces the charge enclosed is zero and hence field at all the points on these surfaces is zero. Thus, electric field in side a hollow sphere of conductor is zero.

Can there be an electric field inside a sphere?

Inside a Sphere of Charge



The spherically symmetric charge outside the radius r does not affect the electric field at r. It follows that inside a spherical shell of charge, you would have zero electric field.

What is the electric field inside a charged sphere?

Note: Since this is a solid sphere , it has charge inside it as well and that is why the electric field is non zero. In case of a hollow spherical shell, the electric field inside the shell is zero .

Why is there no charge in a hollow sphere?

In a hollow sphere, with the charge on the surface of spheres, there is no charge enclosed within the sphere, since all the charges are in surface. Hence there is no electric field within the sphere.

Why there is no charge inside the 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.

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.

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.

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.

Is there an electric field inside a non conductor?

The charge enclosed by such Gaussian surface is zero. Hence, electric field at each point of Gaussian surface is zero. This is true for all Gaussian surfaces having radii between 0 to R where R is inner radius of the shell. Therefore electric field inside a uniformly charged non- conducting spherical shell is zero.

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 meant by non conducting?

a substance that does not readily conduct heat, sound, or electricity.

What is K in electric field?

The Coulomb constant, the electric force constant, or the electrostatic constant (denoted ke, k or K) is a proportionality constant in electrostatics equations. In SI units it is equal to 8.9875517923(14)×109 kg⋅m3⋅s2⋅C2.

What is electric field intensity?

A measure of the force exerted by one charged body on another. Imaginary lines of force or electric field lines originate (by convention) on positive charges and terminate on negative charges.
