Problem: A positive charge of 5.00 mC is fixed in place. From a distance of 4.50 cm a particle of mass 6.60 g and charge +3.90 mC is fired with an initial speed of 62.0 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?
Thanks in advance that solve the above problem.
