Consider two point particles that have charge +e, are at rest, and are separated by 4.10 x 10-15 meter.
(a) Find how much work was required to bring them together from a very large separation distance?
keV (b) If they are released, determine how much kinetic energy will each have when they are separated by twice their separation at release?
keV (c) The mass of each particle is 1.00 u (1.00 amu). Determine what speed will each have when they are very far from each other?
m/s
