9. A charge of 5.0 /C is fixed at the origin and a particle of mass 2.7 g and charge 3.0 /C is initially located at x = 1.0 m. The particle is shot with an initial velocity of 20 m/'s directly toward the fixed charge. How far does the particle travel before it stops and bounces back? 5.0/C 20m/s 3.0AC - - - - - 1.0 m
