Coulomb’s Law Problems - Council Rock School District

17. Two point charges of +2.0 C and +4.0 C are fixed at opposite ends of a meter stick. Where on the meter stick (if anywhere!) could (a) a free electron and (b) a free proton be placed so that they are in electrostatic equilibrium (and won’t move). Place the electron or proton at 41.4 cm, where the 2 C charge is placed at 0cm.
