Four identical particles each have a charge 0.4microC and a mass 0.04kg. They are released from rest at the vertices of a square of side .36m. How fast is each charge moving when their distances from the center of the square doubles? The Coulomb constant is 8.98755 X 10^9 N*m^2/C^2. Answer in units of m/s
