An open capillary tube contains a drop of water. When the tube is in its vertical position, the drop forms a column with a length of a `2cm`, b. `4cm`, and c. `2.98cm`. The internal diameter of the capillary tube is `1mm`. Determine the radii of curvature of the upper and lower meniscuses in each case. Consider the wetting to be complete. Surface tension of water `=0.0075N//m`

Explanation

To determine the radii of curvature of the upper and lower meniscuses in each case, we will follow these steps:

### Given Data:
- Surface tension of water, \( T = 0.0075 \, \text{N/m} \)
- Internal diameter of the capillary tube, \( d = 1 \, \text{mm} \)
- Radius of the capillary tube, \( R = \frac{d}{2} = 0.5 \, \text{mm} = 0.5 \times 10^{-3} \, \text{m} \)
- Density of water, \( \rho = 1000 \, \text{kg/m}^3 \)
- Acceleration due to gravity, \( g = 9.81 \, \text{m/s}^2 \)
