Alpha-particle is a helium nucleus that contains two protons

Reference no: EM13562814

Point A is at a potential of +250 V, and point B is ata potential of –150 V. An Alpha-particle is a helium nucleus that contains two protons and two neutrons; the neutrons are electrically neutral. An Alpha-particle starts from rest at A and accelerates to ward B. When the Alpha-particle arrives at B, what kinetic energy (inelectron volts) does it have?
