Apositron (the electron’s antiparticle) has mass 9.11×10−31 kg and charge q0=+e=+1.60×10−19 c. suppose a positron moves in the vicinity of an α (alpha) particle, which has charge q=+2e=3.20×10−19 c and mass 6.64×10−27 kg. the α particle’s mass is more than 7000 times that of the positron, so we assume that the α particle remains at rest. when the positron is 1.00×10−10 m from the α particle, it is moving directly away from the α particle at 3.00×106 m/s. (a) what is the positron’s speed when the particles are 2.00×10−10 m apart?
