Homework Statement Consider an infinite sheet of parallel wires. The sheet lies in the xy plane. A current I runs in the y-direction through each wire. there are N/a wires per unit length in the x direction. Write an expression for B(d) the magnetic field a distance d above the x y plane...

Never mind, i got the total potential energy. I just have one quick question. What would be the kinetic energy of charge 2q at a very large distance from the other charges? Would the kinetic energy of the charge 2q be the same as the potential energy of the same charge initally? due to...

I thought that was to calculate the total potential energy of the system. Now do you do the same for each charge and add it all together?

I got this question too when I was working on my assignment I was wondering what this part of the question meant What is the contribution U2q to the electric potential energy of the system, due to interactions involving the charge ?
