AIIMS 2018 Physics Electric Field and Potential Assertion Reason Question
Assertion: Electric field is discontinuous across the surface of a spherical charged shell. Reason: Electric potential is continuous across the surface of a spherical charged shell.
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
Correct Answer
Detailed Explanation
The assertion is true because the electric field exhibits a discontinuity at the surface of a charged spherical shell, transitioning from zero inside the shell to a non-zero value outside due to the shell's charge. The reason is also true, as the electric potential remains continuous across the surface, meaning it does not change abruptly despite the electric field's discontinuity. Option A is incorrect because, while both statements are true, the reason does not explain the assertion; rather, it highlights a different aspect of the electric field and potential relationship. Options C and D are incorrect because they misrepresent the truth of both statements.
