1. The problem statement, all variables and given/known data Consider a uniformly charged half spherical shell. The total charge is Q and the radius is R. a) Calculate the electric field as a function of z for – 5R < z < 5R. b) Draw equipotential curves in the xz-plane for – 5R < x, z < 5R with at least 8 equallyspaced curves. 2. Relevant equations 3. The attempt at a solution I solved for the electric fields in the region z>R and z<R so part a) is done. I'm trying to plot this field and the equipotential lines in MATLAB but I couldn't figure out how. I haven't really used MATLAB before but I think MATLAB can definitely do this. I understand that the equipotential lines are perpendicular to the electric field lines. So maybe I can use this fact to draw the equipotential lines...
Investigate the function 'quiver3'. However, I am not sure if it accepts any other coordinate system other than cartesian.
