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...

2. In the derivation of the energy levels in the hydrogen atom one commonly assumes that the nucleus is a point charge. However, in reality the size of the nucleus is of the order of Im = 10-15m. Since this is very much smaller than the typical distance of the electron from the nucleus, which is of the order of a0-0.5A = 0.5 × 10-10m, the finite size of the nucleus can be taken into account perturbatively. (a) Assume that...
