A cylindrical shell of radius 7,00 cm and length 243 m has its charge uniformly distributed on its curved surface. The magnitude of the electric field at a point 18.8 cm radially outward from its axis (measured from the midpoint of the shell) is 36.0 kN/C. (a) Find the net charge on the shell. 1.12E12 If the radius of the shell was reduced to zero, would that affec the field at 18.8 cm from the axis? nC (b) Find the electric field at a point 4.00 cm from the axis, measured radially outward from the midpoint of the shell. 1.26 How much charge is contained inside an imaginary cylinder of radius 4.00 cm? kN/C Need Heln?
