A long straight metal wire of radius r1= 3.30E-2 m is surrounded by a metalic cylindrical shell of inner radius r2= 1.39E-1 m and outter radius r3= 1.84E-1 m. The axes of the wire and the cylindrical shell coincide. The wire carries a charge per unit length 8.20E-6 C/m and the shell carries a charge per unit length -1.64E-5 C/m. Find the magnitude of the electrical field at a position p1= 6.90E-2 m?
