During the Rutherfore.s alpha-particle scattering experiment

Answer»

Distance of closest approach is of the ORDER of `10^(14)m`
At the distance of closest approach, the kinetic energy of the `alpha`-particle is transformed into electrostatic potential
The `alpha`-particles MOVING towards the nucleus will stop and start RETRACING its PATH
Maximum number of `alpha`-particles went STRAIGHT through metal foil
