he cross section of a long coaxial cable is shown in the figure, with radii as given. The linear charge density on the inner conductor is -60 nC/m and the linear charge density on the outer conductor is -90 nC/m. The inner and outer cylindrical surfaces are respectively denoted by A, B, C, and D, as shown. (μ0 = 8.85 x 10-12 C2/N.m2)
What is the linear charge density built up on surface a?
What is the magnitude of the electric field at a point that is 61 mm from the axis?
What is the linear charge density built up on surface c?
Use gausses law to find the magnitude and the direction of the electric field at r=93mm?
