A cylindrical shell of radius 7.00 cm and length 2.57 m has its charge uniformly distributed on its curved surface. The magnitude of the electric field at a point 16.0 cm radially outward from its axis (measured from the midpoint of the shell) is 36.0 kN/C. Required:
a. Use approximate relationships to find thenet charge on the shell.
b. Use approximate relationships to find theelectric field at a point 4.00 cm from the axis, measured radiallyoutward from the midpoint of the shell.
