High Frequency Signals Are Often Transmitted Along a Coaxial Cable,which $\kappa$

question 32

Multiple Choice

High frequency signals are often transmitted along a coaxial cable,which consists of a wire surrounded by an outer grounded conductor.An insulating material fills the space between them and a plastic coating goes around the outside.For one such coaxial cable the radius of the inner wire is 0.5 mm and the radius of the outer conductor is 2.5 mm.The dielectric medium of constant $\kappa$ = 3.7 fills the space between the two conductors.The capacitance per unit length of this coaxial cable is

• A)34.6 pF/m.
• B)49.5 pF/m.
• C)82.9 pF/m.
• D)98.1 pF/m.
• E)127.9 pF/m.
