A liquid drop of diameter 2 mm and surface tension 70 dy `cm^(-1)` is sprayed into 1000 identical small droplets. Calculate the work done in the process.

Explanation

To solve the problem of calculating the work done in spraying a liquid drop into 1000 identical small droplets, we can follow these steps:

### Step 1: Understand the Given Data
- Diameter of the large drop, \( D = 2 \, \text{mm} = 0.2 \, \text{cm} \)
- Radius of the large drop, \( R = \frac{D}{2} = 1 \, \text{mm} = 0.1 \, \text{cm} \)
- Surface tension, \( \gamma = 70 \, \text{dy/cm} \)
- Number of small droplets, \( n = 1000 \)
