100. (a) At the smallest center-to-center separation p d the initial kinetic energy K i of the proton is entirely converted to the electric potential energy between the proton and the nucleus. Thus, 2 lead 18 2 . 44 i pp eq e K dd εε == 00 ππ In solving for p d using the eV unit, we note that a factor of e cancels in the middle line: () ( ) 19 22 92 2 66 0 14 82 1.6 10 C 82 82 8.99 10 N m C 4 4.80 10 V 4.80 10 V 2.5 10 m 25fm . p i ee dk Ke πε × = ×
