A positron (the electron's antiparticle) has mass 9.11 x 10-31kg and charge q0 = +e = +1.60 x 10-19 C. Suppose a positron moves directly away from an alpha particle, which has charge q = +2e. The alpha particle is stationary. When the positron is 1.00 x 10-10 m from the alpha particle, it is moving directly away from the alpha particle at 3.00 x 106 m/s. (a) What is the positron's speed when the particles are 2.00 x 10-10 m...
