I'm doing a practice exam paper and I stumbled upon a question I can't answer for 5 marks.

Describe the advantages of electron scattering over alpha particle scattering. Sketch a graph of charge density vs distance from centre of nucleus. From the graph, explain why protons are more influenced by strong force than coulomb force.

I've been looking around the net and can't seem to find a direct comparison between electron and alpha scattering. I understand that high energy electrons can penetrate the nucleus, I understand that alpa scattering gives closest approach... but where's the real advantage?

Can't seem to find charge density vs distance either

I understand that strong force works at 1fm, disappears at 2.5fm. What range was protons at again? Can't seem to find it.

Help me out please! Exam in few days!

Thanks in advance
