Solve the all parts of given question:
Question: A cylindrical shell of radius 7.00 cm and length 2.41 m has its charge uniformly distributed on its curved surface. The magnitude of the electric field at a point 20.8 cm radically outward from its axis (measured from the midpoint of the shell) is 36.0 kN/C.
Part A: Find the net charge on the shell.
_____________________nC
Part B: Find the electric field at a point 4.00 cm from the axis, measured radically outward from the midpoint of the shell.
_____________________ kN/C
