Multiple-Concept Example 4 provides useful background for this problem. Point A is at a potential of +220 V, and point B is at a potential of -140 V. An a-particle is a helium nucleus that contains two protons and two neutrons; the neutrons are electrically neutral. An a-particle starts from rest at A and accelerates toward B. When the a-particle arrives at B, what kinetic energy (in electron volts) does it have?
