[QUOTE="Miles123K, post: 6148930, member: 650709"] Oh right yes. Thanks for the tip. Now I get it. It's actually three equations instead of two. Here's my solution: By writing out the potentials and cancelling out the constants, I got the following three equations: ##q_1 + \frac 1 2 q_2 + \frac 1 3 q_3 = 0## ##\frac 1 2 q_1 + \frac 1 2 q_2 + \frac 1 3 q_3 = \frac 1 3 Q## ##\frac 1 3 q_1 + \frac 1 3 q_2 + \frac 1 3 q_3 = \frac 1 3 Q## By solving this simultaneous equation I got ##q_1 = - \frac 2 3 Q, q_2 = \frac 2 3 Q, q_3 = Q## ##q_1## is the inner most shell, ##q_2## is the inner surface of the outer shell, ##q_3## is the outer surface of the outer shell.
