A glass rod of diameter `d_(1)=1.5 mm` in inserted symmetrically into a glass capillary with inside diameter `d_(2)=2.0` mm. Then the whole arrangement is vertically oriented and brought in contact with the surface of water. To what height will the liquid rise in the capillary?
Surface tension of water `=73xx10^(-3)N//m`

Explanation

To find the height to which the liquid will rise in the capillary tube when a glass rod is inserted, we can use the formula for capillary rise, which is derived from the balance of forces due to surface tension and the weight of the liquid column.

### Step-by-Step Solution:

1. **Identify the Given Values:**
- Diameter of the glass rod, \( d_1 = 1.5 \, \text{mm} = 1.5 \times 10^{-3} \, \text{m} \)
- Inside diameter of the capillary, \( d_2 = 2.0 \, \text{mm} = 2.0 \times 10^{-3} \, \text{m} \)
- Surface tension of water, \( T = 73 \times 10^{-3} \, \text{N/m} \)
