A positive charge of 5.30 μC is fixed in place. From a distance
of 4.90 cm a particle of mass 5.70 g and charge +3.30 μC is fired
with an initial speed of 70.0 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?
