A cylindrical shell of radius 5.73E-2m and length 2.46m has its charge uniformly distributed on its curved surface. The magnitude of the electric field at a point 0.201m radially outward from its axis (measured from the midpoint of the shell) is 3.13E+4N/C. Use approximate relations to find the net charge on the shell. Find the electric field at a point 0.02cm from the axis, measured radially outward from the midpoint of the shell.
