Two air bubbles are formed in water (surface tension 0.72 N/m). The bubbles come together to form a bigger bubble. What will be radius and sense of curvature of common surface of that bubble? The radii of bubbles are 0.003 m and 0.005 m.

Explanation

To solve the problem of two air bubbles merging into a larger bubble, we will follow these steps:

### Step 1: Understand the Problem
We have two air bubbles in water with given radii:
- Radius of the first bubble, \( r_1 = 0.003 \, \text{m} \)
- Radius of the second bubble, \( r_2 = 0.005 \, \text{m} \)
- Surface tension of water, \( S = 0.72 \, \text{N/m} \)
