View Answer & Solution
Correct answer · Option D
more on smaller sphere
Explanation
Electric potential of a charged conducting sphere is \( V = \frac{kQ}{R} \). Since charges are equal, potential is inversely proportional to radius (\( V \propto \frac{1}{R} \)). Thus, for the smaller sphere (\( R_2 \)), the potential is higher.
