JEE PHYSICS MCQ: ELECTRIC POTENTIAL AND CAPACITANCE

1 Medium

1 of 1

Analyzing +4 | -1

Assertion:- Two adjacent conductors carrying the same charge can be at different potentials.
Reason:- The conductors may have different sizes and hence different capacitances.

View answer and explanation

Correct option: A

If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion

Option A is correct because conductors with the same charge can have different potentials due to different capacitances, which depend on size.
