Thanks Mr. Charles Link. In the first solution i get the q12 -6*10-6q1 -16*10-12 = 0
and for second one i get q12 - 6*10-6q1-16*106 = 0.
My question is why i get different powers for the term involving -16.

"At a distance of 1.5 fermi, the nuclear force becomes maximum and remains attractive in nature. However, at a distance of 0.5 fermi, the nuclear force suddenly becomes repulsive. "
Revered Members,
Nuclear force is a short range force, so naturally when the distance between the nucleons...
