Problem 7: Four charged particles are initially arranged to be at the corners of a square with sides L = 8.75 centimeters. The particles each have a mass of 62.6 x 10-27 kg and they each have a charge of 92.9 × 10-19 Coulombs. Part (a) What is the electric potential energy (in Joules) for this arrangement of particles? PE = Part (b) The particles are released from rest. Assuming no other forces are involved, what is the maximum speed (in m/s) reached by any one of the particles?
