Question:
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:

Show Hint
Remember:
- In electrostatics, excess charge stays on the surface of a conductor
- Electric field inside conductor: \[ E = 0 \]
- Between capacitor plates: \[ E \neq 0 \]

- Both A and R are true and R is the correct explanation of A
- Both A and R are true but R is NOT the correct explanation of A
- A is true but R is false
- A is false but R is true
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
In electrostatics:
Step 1: Analyze Assertion A. Assertion states: “A conductor does not store any net charge inside.” This is true because in electrostatic equilibrium:
Step 2: Analyze Reason R. Reason states that free charge carriers placed between capacitor plates experience force and drift. Between capacitor plates: \[ E = \frac{V}{d} \] Hence an electric field exists, and a charge placed there experiences: \[ F = qE \] Therefore, Reason R is also true.
Step 3: Check whether R explains A. Reason R talks about:
- Excess charge in a conductor resides only on its surface.
- Electric field inside a conductor in electrostatic equilibrium is zero.
Step 1: Analyze Assertion A. Assertion states: “A conductor does not store any net charge inside.” This is true because in electrostatic equilibrium:
- Free electrons move until electric field inside becomes zero.
- Excess charge remains only on the outer surface.
Step 2: Analyze Reason R. Reason states that free charge carriers placed between capacitor plates experience force and drift. Between capacitor plates: \[ E = \frac{V}{d} \] Hence an electric field exists, and a charge placed there experiences: \[ F = qE \] Therefore, Reason R is also true.
Step 3: Check whether R explains A. Reason R talks about:
- Motion of charges between capacitor plates
- Presence of electric field in capacitor region
- Distribution of charge inside a conductor in electrostatic equilibrium
