Helium nucleus that contains two protons and two neutrons

Reference no: EM13565032

Point A is at a potential of +250 V, and pointB is at a potential of -140V. An α-particle is a helium nucleus that contains two protons and two neutrons; the neutrons are electrically neutral. An α-particle starts from rest at A and accelerates toward B. When theα-particle arrives at B, what kinetic energy(in electron volts) does it have?
