The potential energy of the strong interaction between two quarks has the approximate form V(r)=br, where b is some constant. Assume that we have a light quark of mass m interacting with a very massive quark. using the same basic approach that we used for the Bohr model, find the possible energies and effective radii of this system. if the light quark and b=150000N. estimate the minimum radius of the lighter quark's effective "orbit". (Find En, rn, and minimum radius)
