43. (a) The magnitude of the force on the particle is given by F= qE, where qis the magnitude of the charge carried by the particle and Eis the magnitude of the electric field at the location of the particle. Thus, EFq==××=×−−30 1020 1015 10693...NCNC.The force points downward and the charge is negative, so the field points upward. (b) The magnitude of the electrostatic force on a proton is ()( )193161.60 10C1.5 10 N C
