A mercury drop of radius `R` is sprayed into `n` droplets of equal size. Calculate the energy expanded if surface tension of mercury is `T`.

Explanation

To solve the problem of calculating the energy expended when a mercury drop of radius \( R \) is sprayed into \( n \) droplets of equal size, we can follow these steps:

### Step 1: Calculate the Initial Surface Area
The initial surface area \( A_{\text{initial}} \) of the mercury drop with radius \( R \) is given by the formula for the surface area of a sphere:
\[ A_{\text{initial}} = 4 \pi R^2 \]
