A parallel plate capacitor, with a surface charge density of 23.7 micro-Coulomb/m2 is aligned such that its plates are parallel to the y axis. A point charge of -29 micro-Coulombs is fired in the +x direction at 14.1 m/s toward the negative plate. If the mass of the point charge is 5.5 kg, how far does the charge travel before it stops due to the electric force alone (ignore weight force)? Answer in meters
