Given the mass of one object as 3.00 X 10^ -3 kg and
the mass of a second object as 6.00 X 10 ^ -3 kg (both
objects have the same charge of 8.00 X 10^ -6 C) when
released the radius between the two becomes 0.100 m
and the object with a mass of 3.00 X 10^ -3 kg reaches a
velocity of 125 m/s. How do you find the original radius?
