Consider an infınite line of charge with charge per length equal to 6 nC/m. This line of charge is surrounded by cylindrical shell of charge with charge per length equal

to 0.6nC/m and radius 4 m. Calculate the magnitude of the electric field 7.2 m from the line ofc harge, in N/C. If the electric field points inward, your answer should be negative. UseE0 = 8.9 x 10-12 F/m.
