1. The problem statement, all variables and given/known data A cylindrical shell of radius 7.00 cm and length 260 cm has its charge uniformly distributed on its curved surface. The magnitude of the electric field at a point 20.0 cm radially outward from its axis (measured from the midpoint of the shell) is 36.0 kN/C. Find values for the following. (a) the net charge on the shell (b)the electric field at a point 4.00 cm from the axis, measured radially outward from the midpoint of the shell 2. Relevant equations E = Q/(4π r² εo) 3. The attempt at a solution This problem is giving me such a headache. I thought you just have to rearrange the above equation to solve for Q as that is the total charge but I'm wrong. I don't understand what's going on conceptually with all these gaussian problems. I looked at online and book figures and it's just not clicking yet. PLEASE help!
