Question: A positive charge of 5.00 µC is fixed in place. From a distance of 3.70 cm a particle of mass 6.40 g and charge +3.50 µC is fired with an initial speed of 70.0 m/s directly toward the fixed charge.
Part A: How close to the fixed charge does the particle get before it comes to rest and starts traveling away?
