Equilibrium position for a negative charge due to two positive charges can be obtained when the negative charge is placed on the line joining the two positive charges, inside the two charges and nearer to the smaller charge.If x is the distance of the negative charge form the smaller charge and d be the distance between the positive charges, the equilibrium position can be found by the equation
k*Q1/x^2 = k*Q2/(d - x)^2.
This position is independent of the magnitude of the negative charge.
