The nucleus of 8be, which consists of 4 protons and 4 neutrons, isvery unstable and spontaneously breaks into two alpha particles(helium nuclei, each consisting of 2 protons and 2 neutrons). (a)what is the force between the two alpha particles when they are5.00 x 10-15m apart, and (b) what will be the magnitudeof the acceleration of the alpha particles due to this force? notethat the mass of an alpha particle is 4.0026 u.
