1. Predict the minumum speed of a 20.0MeV proton as it passes within 1.0x10^-13 meters of a lead nucleus having 82 protons. (Note: 1eV = 1.6x10^-19 Joules)
2. How do I start off?
3. All i can think of is to get a charge for the lead nucleus by using q=ne which is the number of electrons/protons multiplied by the fundamental charge(1.6x10^-19) and also convert the MeV into joules using the note given at the end of the question.
