It is known that the gravitational force of attraction between two alpha particles is much weaker than the electrical repulsion. For two alpha particles at a distance d apart, calculate the ratio of the size of the gravitational attraction to that of the electrical repulsion. Specifically, find the magnitude of Gravitational/Electrical.
