A menisus drop of radius 1 cm sprayed into `10^(5)` droplets of equal size . Calculate the energy expended if surface tension of mercury is `435 xx10^(-3)` N/m

Explanation

To solve the problem, we need to calculate the energy expended when a meniscus drop of mercury is sprayed into \( 10^5 \) droplets of equal size.

### Step-by-Step Solution:

1. **Identify the Given Values:**
- Initial radius of the mercury drop, \( R = 1 \, \text{cm} = 0.01 \, \text{m} \)
- Number of droplets, \( N = 10^5 \)
- Surface tension of mercury, \( \gamma = 435 \times 10^{-3} \, \text{N/m} \)
