When a third charge q₀ is inserted on the line between two charges, Q₁ and Q₂, each having the same sign, the position at which q₀ is in equilibrium between Q₁ and Q₂ does not depend on the sign or magnitude of q₀.

Question

Quizplus · Accepted Answer

The equilibrium position of the third charge depends on the relative magnitudes and positions of the two fixed charges, not on the sign or magnitude of the third charge, due to the principle of superposition in electrostatics.
