A water drop of radius

1 \mathrm{~cm}

is broken into 1000 equal droplets. What would be the gain in surface energy, if the surface tension of water is

0.075 \mathrm{Nm}^{-1}

View answer and explanation

Correct option: B

8.48 \times 10^{-4} \mathrm{~J}

Option B (

8.48 \times 10^{-4} \mathrm{~J}

) is correct because it is the calculated gain in surface energy when a water drop breaks into smaller droplets, considering the increase in surface area.
