Lines оf chаrge: The crоss sectiоn of а long coаxial cable is shown in the figure, with radii as given. The linear charge density on the inner conductor is -30 nC/m and the linear charge density on the outer conductor is -70nC/m. The inner and outer cylindrical surfaces are respectively denoted by A, B, C, and D, as shown. (
