A small drop of water kept pressed between two glass plates spreads as a circle of diameter 10cm. If the distance between the plates is 0.005 mm, and surface tension of water is `0.072 Nm^(-1)` , what force will be required to separate the plates ?

Explanation

To solve the problem of finding the force required to separate two glass plates with a drop of water in between, we can follow these steps:

### Step 1: Convert the given measurements to SI units
- The distance between the plates \( D \) is given as \( 0.005 \, \text{mm} \). To convert this to meters:
\[ D = 0.005 \, \text{mm} = 0.005 \times 10^{-3} \, \text{m} = 5 \times 10^{-6} \, \text{m} \]
