Two concentric conducting spheres of radii r 1 and r 2 (r 1 < r 2 ) carry electric charges of + Q and – Q respectively. The region between the sphere is filled with two insulating layers of dielectric constant ε 1 and ε 2 and width d 1 and d 2 respectively. Variation of potential and electric field with radial distance from O is given. Select the correct one. (assume Vat r 2 = 0)
