In a Geiger- Marsden experiment, calculate the distance of closest approach to the nucleus of Z=80, when an `alpha` particle of 8 Me V energy impinges on it before it comes momentarily to rest and reverses its direction. How will the distance of closest approach be affected when the kinetic energy of the `alpha-` particle is doubled ?
