The 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 -10 Cm and the linear charge density on the outer conductor is -60 nC/m. The inner and outer cylindrical surfaces are respectively denoted by A, B, C, and D, as shown. (60 = 8.85 10-12 C2/N .m2) The radial component of the electric field at a point that 34 mm from the axis is closest to D A 28 mm 30 mm 19 mm 51 mm A) -5300 NC B) -32,000 NC
1 mm A) -5300 N/C. B) -32,000 N/C. C) +5300 N/C. D) +32,000 N/C. E) zero Your answer: G A B D E Correct result is not given in choices
