Question

Two protons P and two positrons e+ are assembled at the corners of a square of side 1 um as shown below. Each of these particles has a positive charge of q=+e, where e = 1:6022X10 ^-19 C is the fundamental charge, but the proton is much more massive: the mass of the proton is mP=1:67261X 10 ^-27 kg while the mass of the positron equals the mass of the electron, me = 9:1094X 10 ^ -31 kg. a) What total work is required to assemble these charges in the above configuration, by bringing the charges in from infinity? b) If all of the particles are released from rest at time t=0, what are their final speeds? [Hint: Use energy conservation, and assume that the protons are so much more massive than the positrons that they remain essentially stationary during the time it takes for the positrons to reach their final speeds.] 2
