An air-filled capacitor is charged, and then a dielectric is inserted.As a result, there is an induced charge on the dielectric.What is the difference between induced charge and free charge?
A)There is no difference.
B)Induced charge does not result in a net charge on the dielectric.
C)Induced charge is smaller than free charge.
D)Free charge creates an electric field, but induced charge does not.
E)Free charge creates an electric potential, but induced charge does not.

Induced charge refers to charges that are redistributed within a material due to the presence of an external electric field. In the case of a dielectric being inserted into a charged capacitor, the electric field polarizes the molecules of the dielectric, causing the charges within the material to redistribute. However, this does not result in a net charge on the dielectric, meaning that there is no free charge present. Therefore, option B is correct.
