NEET Physics Potential MCQ Question
The potential of a large liquid drop when eight liquid drops are combined is 20 V, then the potential of each single drop was
10 V
7.5 V
5 V
5 V
Correct Answer
Detailed Explanation
The potential of a drop is proportional to its radius. When eight drops combine, the radius becomes 2 times, and potential becomes 2 times. Hence, the potential of each drop was 7.5 V.
