Suppose an attractive nuclear force acts between two protons which may be written as F = Ce-kr/r2 (a) Write down the dimensional formulae and appropriate SI units of C and k. (b) Suppose that k = 1 fermi -1 and that the repulsive electric force between the protons is just balanced by the attractive nuclear force when the separation is 5 fermi. Find the value of C.

Expression of electrical force F = C x e-kr/r2
Since e–kr is a pure number. So, dimensional formulae of F =dimensional formulae of C/dimensional formulae of r
