Question

In the given question, a statement of Assertion $\left(A\right)$ is given, followed by a corresponding statement of Reason $\left(R\right)$ just below of it. Mark the correct answer.

Assertion$\left(A\right)$ : An uncharged conducting slab is placed normally in a uniform electric field. The resultant electric field inside the slab is zero.

Reason$\left(R\right)$ : The charge in the conductor exists only on its surface

• A. Both $\left(A\right)$ and $\left(R\right)$ are true and $\left(R\right)$ is the correct explanation of $\left(A\right)$
• B. Both $\left(A\right)$ and $\left(R\right)$ are true and $\left(R\right)$ is not the correct explanation of $\left(A\right)$
• C. $\left(A\right)$ is true and $\left(R\right)$ is false
• D. $\left(A\right)$ is false and $\left(R\right)$ is true

Answer 1

The correct option is A Both $\left(A\right)$ and $\left(R\right)$ are true and $\left(R\right)$ is the correct explanation of $\left(A\right)$

Electric field is zero inside a charged conductor.

For a charged conductor, the charges will lie on the surface of the conductor.So, there will not be any charges inside the conductor. When there is no charge there will not be electric field.
