In a Geiger - Marsden experiment, calculate the distance of closest approach to the nucleus of Z=75, when an `alpha` - particle of 5 Me V enery 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 ?
