- 3) Use the Weizsäcker formula to calculate the binding energy for 28Ni60.1. There are 82 protons in a lead nucleus. Why doesn't the lead nucleus burst apart? a) Coulomb repulsive force doesn't act inside the nucleus b) gravity overpowers the Coulomb repulsive force inside the nucleus c) the negatively charged neutrons balance the positively charged protons d) protons lose their positive charge inside the nucleus d) None of the other responses are correct2) Calculate the density of the nucleus if it had a radius of 10 cm.
