Two identical small charged spheres, each having a mass m, hang in equilibrium as shown in fig. the ligth of each string is l, and the angle made by any string with the vertical is `theta`. Find the magnitude of the charge on each sphere.

Explanation

To solve the problem of finding the magnitude of the charge on each of the two identical small charged spheres hanging in equilibrium, we can follow these steps:

### Step-by-step Solution:

1. **Identify the Forces Acting on the Spheres:**
Each sphere experiences three main forces:
- The gravitational force (weight) acting downward: \( F_g = mg \)
- The tension in the string (\( T \)) acting along the string at an angle \( \theta \) to the vertical.
