In a Rutherford scattering experiment, an alpha particle of energy 4.79 Mev is aimed directly at a gold nucleus. The alpha particle has a charge of +2e while
the gold nucleus has 79 protons and a charge of +79e.
Write down an expression for the Coulomb force of repulsion when the alpha particle and the nucleus are separated by distance r.
Integrate this expression from the starting point (infinite separation) to the distance of closest approach to calculate the work done by the electrostatic force to slow the particle to zero velocity.
By equating the work done to the energy
