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

Options

  1. ABoth A and R are true and R is the correct explanation of A
  2. BBoth A and R are true but R is NOT the correct explanation of A
  3. CA is true but R is false
  4. DA is false but R is true

Correct answer

B. Both A and R are true but R is NOT the correct explanation of A

Step-by-step solution

In electrostatics, the electric field inside a conductor is zero. According to Gauss's law, E d s = q_ in ₀ . Since E = 0 everywhere inside the conductor, the net charge enclosed q_ in must be zero. Thus, a conductor does not store any net charge inside its bulk, and any excess charge resides only on its surface. Assertion A is true. Inside a capacitor with no dielectric medium, a uniform electric field exists between the plates. If free charge carriers are placed in this region, they will experience an electrostat
