Exploring Creation with Physics 2nd edition module 14 practice problem 7: a +3.8mC charged particle (m=5.0kg) is shot with an initial velocity of 245 m/sec towards a +1.5mC stationary charge. If the particle starts out 1.2 meters from the stationary charge, how close will it come to the charge before stopping and moving away? Also, does anyone know where I could find this solution key for free online? Thanks!
