A particle with mass M and charge +e and its antiparticle (same mass M. charge-e) are initially at rest, far from each other. They attract each other and move toward each other.

(d) Now consider a specific case: a proton and an antiproton, each with an initial speed of 5.2 x 10 m/s when they are far apart. When these two particles collide, they react to form two new particles: a positive pion (*.charge +e) and a negative pion (x,charge-e). Each pion has a rest mass of 2.5x 10.28 kg.
