Chapter 24, Problem 101(choose chapter or problem)
In the quark model of fundamental particles, a proton is composed of three quarks: two up quarks, each having charge 2e/3, and one down quark, having charge e/3. Suppose that the three quarks are equidistant from one another. Take that separation distance to be 1.32 1015 m and calculate the electric potential energy of the system of (a) only the two up quarks and (b) all three quarks.
