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. a) Take the distance to be 1.14×10-15 m and calculate the potential energy of the subsystem of two "up" quarks. (MeV)  b)Calculate the total electric potential energy of the three-particle system. (MeV

A point charge q, = 5.28 x 106C is held fixed at the origin of a coordinate system. A second charge q2 = -3.96 x 106 C is initially at the coordinates (0.149, 0) m and is then moved to the coordinates (0.211, 0) m. What change in potential energy results from moving q2?

I have a question regarding two charges on an axis. The problem is as follows: Two particles each with charge +1.79 µC are located on the x axis. One is at x = 1.00 m, and the other is at x = −1.00 m. (a) Determine the electric potential on the y axis at y = 0.520 m. (b) Calculate the change in electric potential energy of the system as a third charged particle of -3.81 µC is brought from infinitely far away to a position on the y axis at y = 0.520 m.

A point charge q1= 2.40 uC is helf stationary at the origin. A second point charge q2= -4.30 uC moves from the point ×=0.150m, y=0 to the point ×=0.250, y=0.250. Calculate the change in three electrical potential energy between the charges.
