Suppose ana attractive nuclear force act...

Suppose ana attractive nuclear force acts between two protons which may be written as `F = Ce^(-kr) //r^2,` (a) Write down the dimensional formulae and appporpriate SI units of C and k. (b) Suppose that `k = 1 fermi^(-1)` and that the repulsive electreic force between the protons is just blanced by the attractive nuclear force when the separation is 5 fermi. Find the value of c.
