This following is Three charges in static equilibrium
Created by prof Hwang Modified by Ahmed
Original project Three charges in static equilibrium

Assume there are three changes with mass m1,m2,m3 and charge q1,q2,q3
There are attached to each other with strings and hanged on top of ceiling. All the strings are the same length.
The following simulation calculate static equilibrium positions.

Assume the mass from the top to the bottom are $m_1$,$m_2$,$m_3$, the tension of the string are $T_1$,$T_2$,$T_3$.
The condition for equilibrium are
1. T_{3x}= q_3 E and T_{3y}= m_3 g
2. T_{2x}= (q_2+q_3) E and T_{2y}= (m_3+m_2) g
3. T_{1x}= (q_1+q_2+q_3) E and T_{1y}= (m_3+m_2+m_1) g
