If both the Assertion and the Reason are true but the Reason is not a correct explanation of Assertion. C. If the Assertion is true but the Reason is false. D. If both the Assertion and the Reason are false. E. If Assertion is false but Reason is true.

Assertion: A metallic shield in form of a hoi; shell may be built to block an electric field. Reason: In a hollow spherical shield, t: electric Held inside it is zero at every point.

A) A       

B)                        B            

C)                        C                            

D)        D           

E) E

Correct Answer: A

Solution :

                Electric field created due to a charge may be blocked by a metallic shield in the form of a hollow shell, because at every point on the surface the potential will be the same. Hence, electric field inside the spherical charge is zero everywhere.
