Thank you. Yes, that would be great if you could give me enough knowledge to make the equations and solve them. I can solve basic integrals but just them. I can't solve the complex ones. Also I would be such pleased if someone check my equations and answer after I learned and worked out the...
Let's say there is two tubes(cylinders with no tops or bottoms) with charges ##q_1## and ##q_2##, radii ##b_1## and ##b_2##, lengths ##l_1## and ##l_2##. These tubes are located along the axis of each other's surfaces like in this figure:
I know I have to use Coulomb's law rather than Gauss law...
