Two indentical pith balls, each carrying charge q, are suspended from a common point by two strings of equal length l. Find the mass of each ball if the angle between the strings is `2theta` in equilibrium.

Explanation

To find the mass of each pith ball suspended at an angle of \(2\theta\) in equilibrium, we can follow these steps:

### Step 1: Understand the Geometry
We have two identical pith balls, each carrying a charge \(q\), suspended from a common point by strings of equal length \(l\). The angle between the strings is \(2\theta\). This means each string makes an angle \(\theta\) with the vertical.

### Step 2: Identify Forces Acting on the Balls
Each ball experiences three forces:
1. Tension \(T\) in the string.
