Question

Read the assertion and reason carefully to mark the correct option out of the options given below : 

(a) If both assertion and reason are true and the reason is the correct explanation of the assertion. 

(b) If both assertion and reason are true but reason is not the correct explanation of the assertion. 

(c) If assertion is true but reason is false. 

(d) If the assertion and reason both are false. 

(e) If assertion is false but reason is true. 

Assertion: A metallic shield in form of a hollow shell may be built to block an electric field. 

Reason: In a hollow spherical shield, the electric field inside it is zero at every point.

Answer 1

The correct option (a) If both assertion and reason are true and the reason is the correct explanation of the assertion.

Explanation:

In a hollow spherical shield, the electric field is zero at every point. Hence metallic shield in the form of hollow shell may be built to block electric field. 

hence both are true & reason is correct explanation of assertion.
