Question 1
The radius of a nucleus of is . Suggest why there will be no deviations from Rutherford scattering in the experiment in (b)(i).
The radius of a nucleus of 82207 Pb is 7.1×10−15 m. Suggest why there will be no deviations from Rutherford scattering in the experiment in (b)(i).
The closest approach is «significantly» larger than the radius of the nucleus / far away from the nucleus/OWTTE.
«Therefore» the strong nuclear force will not act on the alpha particle.
