Expert Answer:

It is the distance from nucleus at which an energetic -particles approaching directly towards the nucleus, retraces its pass through 1800. At distance of closest approach speed of -particles is zero.At the instant of closest approach the initial kinetic energy of the particle will be completely converted into electric potential energy.
