Find the work done in spraying a drop of water of 2mm diameter into a million droplets all of the same size. Surafce tension of water is 72 dyne `cm^(-1)`.

Explanation

To solve the problem of finding the work done in spraying a drop of water of 2 mm diameter into a million droplets of the same size, we will follow these steps:

### Step 1: Convert the Diameter to Radius
The diameter of the big drop is given as 2 mm. To find the radius, we convert the diameter to meters and divide by 2.

\[ \text{Diameter} = 2 \, \text{mm} = 2 \times 10^{-3} \, \text{m} \]
