In a system of three collinear charges, the net electric force on a particular charge is zero when —
- aall three charges have equal magnitude
- bthe algebraic sum of the forces exerted on it by the other two charges is zero
- cthe field at that location is infinite
- dit is at the midpoint of the line, regardless of the values of the charges
