The Cross Section of a Long Coaxial Cable Is Shown

Question 1035

Multiple Choice

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 -40 nC/m and the linear charge density on the outer conductor is
-50 nC/m.The inner and outer cylindrical surfaces are respectively denoted by A,B,C,and D,as shown.(ε0 = 8.85 × 10-12 C2/N • m2) The magnitude of the electric field at a point that is 94 mm from the axis is closest to 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 -40 nC/m and the linear charge density on the outer conductor is -50 nC/m.The inner and outer cylindrical surfaces are respectively denoted by A,B,C,and D,as shown.(ε<sub>0</sub> = 8.85 × 10<sup>-12</sup> C<sup>2</sup>/N • m<sup>2</sup>) The magnitude of the electric field at a point that is 94 mm from the axis is closest to A) 17,000 N/C.
