Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R
Assertion A : In electrostatics, a conductor does not store any net charge inside.
Reason R : Inside the capacitor (with no dielectric medium), the free charge carriers, if placed between the plates of capacitor, experience force and drift.
Choose the correct answer from the options given below
Answer: (B) Both $\mathbf{A}$ and $\mathbf{R}$ are true but $\mathbf{R}$ is NOT the correct explanation of $\mathbf{A}$
A is true: in electrostatic equilibrium the field inside a conductor is zero, so by Gauss's law there is no net charge inside; any excess charge sits on the surface.
R is true: between the plates of a charged capacitor there is a field, so a free charge placed there feels a force and drifts.
But R talks about the gap of a capacitor, not the interior of a conductor, so it does not explain A.
