A 2.35-nC charged particle located at the origin is separated by a distance of 0.0930 m from a 3.78-nC charged particle located farther along the positive x axis. If the 2.35-nC particle is kept fixed at the origin, where along the positive x axis should the 3.78-nC particle be located so that the magnitude of the electrostatic force it experiences is twice as great as the magnitude of the electrostatic force it experiences at 0.0930 m? m
