A positive charge of 4.20 ?C is fixed in place. From a distance of 3.50 cm a particle of mass 6.20 g and charge +4.00 ?C is fired with an initial speed of 68.0 m/s directly toward the fixed charge. How close to the fixed charge does the particle get before it comes to rest and starts traveling away?
