AIIMS 2018 Physics Conductors and Insulators MCQ Question
Assertion: All the charge in a conductor gets distributed on whole of its outer surface.
Reason: In a dynamic system, charges try to keep their potential energy minimum
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
In electrostatics, charges within a conductor redistribute themselves to minimize potential energy, which occurs when they occupy the outer surface. This distribution is due to the repulsive forces between like charges, leading to a uniform surface charge density that ensures the electric field inside the conductor remains zero. Option B is incorrect because it contradicts the established principle of charge distribution in conductors, while options C and D are irrelevant as the behavior of charges is consistent across all conductors and does not depend on the nature of the charge.
