Nuclear Force

Identify the correct statement // statements a) At greater distances nuclear forces are negligible b) Nuclear forces are non central forces c) Nuclear forces are weakest in nature d)Nuclear forces are charge dependent forces

All nuclei consist of two types of particles- protaon and neutrons. Nuclear force is the strongest froce. Stability of nucleus is determined by the neutron - proton ratio or mass defect or binding energy per nucleus or packing fraction. Shape of nucleus is calculated by quadrupole moment. Spin of nucleus depends on even or odd mass number. Volume of nucleus depends on the mass number. Whole mass of the atom (nearly 99 % ) is centered at the nucleus. Magnetic moment of the nucleus is measured in terms of the nuclear magnetons. The correct statements about nuclear force is/are

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.
