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 the distance to be 1.30×10-15 m and calculate the potential energy of the subsystem of two "up" quarks. (MeV)
Calculate the total electric potential energy of the three-particle system. (MeV)
