Unformatted text preview: meters from the gold nucleus, what is the magnitude of the force of repulsion between the two particles at that point. 3) The electron and proton of a hydrogen atom are separated by a distance of about 5.3 x 10-11 m as shown below. (a) Find the magnitude and direction of the electric force acting on the electron. 4) A +2 Coulomb charge and a +3.5 Coulomb charge are placed along the x axis as shown. Determine where another charge could be placed, besides at infinity so it experiences no net electrostatic force. Proton Electron 5 . 3 x 1-m +2 C +3.5 C 1 2 3 5 6-3 -2 -1 x axis (m) y axis...
