A 10 M Long Piece of Coaxial Cable Has a Wire

Multiple Choice

A 1.0 m long piece of coaxial cable has a wire with a radius of 1.1 mm and a concentric conductor with inner radius 1.3 mm.The area between the cable and the conductor is filled with a dielectric.If the voltage drop across the capacitor is 6000 V when the line charge density is 8.8 μC/m,find the value of the dielectric constant.(k = 1/4πε₀ = 8.99 × 10⁹ N • m²/C²)
