A water drop of radius 1 mm is broken into `10^(6)` identical drops, surface tension of water is 72 dynes/cm find the energy spent in this process.

Explanation

To solve the problem of finding the energy spent in breaking a water drop of radius 1 mm into \(10^6\) identical drops, we can follow these steps:

### Step 1: Determine the Initial Volume of the Drop
The volume \(V\) of a sphere is given by the formula:
\[ V = \frac{4}{3} \pi r^3 \]
For the initial drop with radius \(r = 1 \text{ mm} = 1 \times 10^{-3} \text{ m}\):
