The radii of two capillary tubes A and B are in the ratio of 3:1. If water rises to a height of 3 cm in tube A, how much it will rise in tube B. If the tube A is inclined at an angle of `30^(@)` with the vertical, then what will the position of water in the tube.

Explanation

To solve the problem, we need to find two things:
1. The height of water in capillary tube B (HB) when the height of water in tube A (HA) is given as 3 cm.
2. The position of water in tube A when it is inclined at an angle of 30 degrees with the vertical.

### Step 1: Understanding the relationship between the heights and radii of the capillary tubes
The height of liquid in a capillary tube is given by the formula:
\[ H = \frac{2 \sigma \cos \theta}{r \rho g} \]
Where:
