Question

If 1000 droplets each of potential 1 V and radius \( r \) are mixed to form a big drop, then the potential of the drop as compared to small droplets will be?

• A. 1000 V
• B. 800 V
• C. 100 V
• D. 20 V

Hint:

When droplets combine to form a larger drop, the potential decreases as the radius of the combined drop increases.

Answer 1

The Correct Option is C

The potential of a drop is proportional to its radius, and when droplets combine to form a larger drop, the potential decreases by a factor related to the number of droplets and their size.
