Which of the following statements about conductors and insulators are true? Select all that apply.Question 4Answera.In conductors, some electrons can move around relatively freely. In insulators, electrons can only move by small amounts as they are bound to individual atoms.b.Neutral conductors and insulators can never experience electrostatic forces.c.In conductors, both positive and negative charges can move relatively freely.d.In conductors, all excess charge is on the surface of the conductor.e.The only conducting materials are solid metal.

In a perfect conductor, charge carriers can move freely. Because of this property one is led to conclude that in electrostatic equilibriumSelect one:a.the net charge on the conductor is distributed uniformly throughout its volume.b.there is a constant non zero electric field throughout the volume of the conductor.c.the electric field is zero everywhere thoughout the volume of the conductor.d.a conductor cannot carry a net charge.e.none of the above.

Assertion (A): Dielectric materials are insulators.Reason (R): Dielectric materials do not allow free movement of charges.a) Both A and R are true, and R is the correct explanation of A.b) Both A and R are true, but R is not the correct explanation of A.c) A is true, but R is false.d) A is false, but R is true.

Which of the following statements about the nature of electrical charge is FALSE?  Group of answer choicesElectrical charge is a fundamental property of protons and electrons.Positive and negative electrical charges attract each other.Positive-positive or negative-negative charges repel each other.Positive and negative charges cancel each other so that a proton and electron, when paired, are charge neutral.All of the above statements are true

Assertion (A): The electric field inside a conductor in electrostatic equilibrium is zero.Reason (R): Charges inside a conductor move to the surface to minimize potential energy.a) Both A and R are true, and R is the correct explanation of A.b) Both A and R are true, but R is not the correct explanation of A.c) A is true, but R is false.d) A is false, but R is true.
