Need a little physics help.?

Question

I am having trouble with this particular problem of the section.

An alpha particle (Z = 2, mass 6.64 10-27 kg) approaches to within 1.10 10-14 m of a carbon nucleus (Z = 6).
(a) What is the maximum Coulomb force on the alpha particle?

(b) What is the acceleration of the alpha particle at this point?

(c) What is the potential energy of the alpha particle at the same time?

Answer 1

Use Coulomb's law.
