1. Before we go through with tonight's plans we would like to briefly talk about our family history. That is, the meeting of Proton (e+) and Neutron to acquiring our child, Electron (e-). BUT, to make sure you are one of us, and not just our decadent next meal, you must answer our questions. The real question is this, will get to eat, or get eaten? (a) Explain the analogy between Coulomb's law and Newton's law of gravita- tional force. How does one draw a free body diagram between two charges on a line? (b) Mr. Neils Bohr got it all wrong with his model of the atom. Electrons do not orbit in a circular path, and if they did, what would their velocity be? Express velocity v starting from equating uniform circular motion to Coulomb force. How fast is Electron moving?
