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 with a radius of 1 cm is sprayed into \(10^5\) droplets of equal size. The surface tension of mercury is given as \(435 \times 10^{-3}\) N/m.

### Step-by-Step Solution:

1. **Understanding Volume Conservation**:
The volume of the original drop will be equal to the total volume of the smaller droplets. The volume \(V\) of a sphere is given by:
\[
V = \frac{4}{3} \pi R^3
