A water drop of diameter 2 cm is broken into 64 equal droplets. The surface tension of water is

0.075\,\,N/m.

In this process the gain in surface energy will be

View answer and explanation

Correct option: A

2.8 \times {10^{ - 4}}J

Option A (

2.8 \times {10^{ - 4}}J

) is correct because it is calculated by finding the change in surface area and multiplying it by the surface tension.
