A co-axial cylindrical capacitor shown in Figure (i) has dielectric with relative permittivity ₁₁ = 2. When one-fourth portion of the dielectric is replaced with another dielectric of relative permittivity E₁2, as shown in Figure (ii), the capacitance is doubled. The value of 2 is r R Er1=2 R &r=2 82
