Radium decomposes radioactively to form radon atomic number


Radium decomposes radioactively to form radon (atomic number 86, which is also the number of protons in the nucleus) by emitting an alpha-particle from its nucleus.The mass of an alpha-particle is 6.6404 x 10^-24 grams.What is the force of repulsion between the radon nucleus and the alpha-particle, when the distance between them is 5 x 10^-11 cm? What is the acceleration of the alpha-particle at this distance?
