A liquid of diameter D breaks up into 64 tiny drops. If the surface tension of the liquid is `sigma ` what is the change in energy?

Explanation

To find the change in energy when a liquid drop of diameter \( D \) breaks up into 64 tiny drops, we can follow these steps:

### Step 1: Understand the Problem
We have a single liquid drop of diameter \( D \) that breaks into 64 smaller drops. We need to calculate the change in surface energy due to this process.

### Step 2: Calculate the Radius of the Original Drop
The radius \( R \) of the original drop can be calculated from the diameter \( D \):
\[
