Problem 19. Two electrons, initially at rest, are separated by a distance of 101 m. A) Find the potential energy stored in this configuration. B) Find the final total kinetic energy if the electrons fly (infinitely) far apart. Express your answer in Joules and in eV. C) Find the speed of each electron after they have flown far apart. (Hint: Each electron ends up with 1/2 of the total kinetic energy.)
