A positive charge of 4.00 μC is fixed in place. From a distance of 4.00 cm a particle of mass 5.30 g and charge +3.00 μC is fired with an initial speed of 76.0 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?
