Question 50
EEMCQ2 marksNeeds review
An air filled cylindrical capacitor (capacitance
) of length L, with a and b as its inner and outer radii, respectively, consists of two coaxial conducting surfaces. Its cross-section view is shown in Fig. (i). In order to increase the capacitance, a dielectric material of relative permittivity
is inserted inside 50% of the annular region as shown in Fig. (ii). The value of
for which the capacitance of the capacitor in Fig. (ii), becomes
is
