GATE PH 2021 PH Q31: Electromagnetic Theory

Consider two concentric conducting spherical shells as shown in the figure. The inner shell has a radius

and carries a charge +Q. The outer shell has a radius

and carries a charge

. The empty space between them is half-filled by a hemispherical shell of a dielectric having permittivity

. The remaining space between the shells is filled with air having the permittivity

The electric field at a radial distance

from the center and between the shells (

) is
