141EO 2. A) Two small metal spheres, each carrying charge + 40 PC and with mass 2 grams, are very far apart, but are moving directly towards each other - each having speed 300 m/sec. What is their total energy at this "infinite" position ? (Hint: be careful what units you use for mass, list energy unit with answer. Total Energy B) As they get closer, they will slow down due to Electrostatic interaction. How close will they come together...
