The nucleus of 8Be, which consists of 4 protons and 4 neutrons, is very 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 are 6.40 x 10-15 m apart?
(b) What is the initial magnitude of the acceleration of the alpha particles due to this force?
Note that the mass of an alpha particle is 4.0026 u.
