If current flowing in the cell placed in tangent galvanometer is increased by three times then what will be new angle of deflection if initial angle is `30^(@)` ?

Explanation

To solve the problem, we will use the relationship between the current flowing through a tangent galvanometer and the angle of deflection. The key relationship is that the current (I) is directly proportional to the tangent of the angle of deflection (θ).

### Step-by-Step Solution:

1. **Identify the Initial Conditions**:
- The initial angle of deflection, \( \theta_1 = 30^\circ \).
- The initial current, \( I_1 = I \).
