Question

Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R
Assertion(A): Electric field is discontinuous across the surface of a spherical charged shell
Reason (R): Electric potential is continuous across the surface of a spherical charged shell
In the light of the above statements, choose the correct answer from the options given below

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (B)

If both assertion and reason are true but reason is not the correct explanation of assertion

Answer 2

Electric field is zero inside the spherical charged shell and it is $\frac{\sigma}{\varepsilon_{0}} \pi$ outside.
So it is discontinuous across the surface. Electric potential is continuous across the surface.
As, $V=\frac{1}{4\pi \, \in_{0}} \frac{q}{r}, r \, \le\,R$
