Spherical conductor with two linear and uniform dielectrics with relative permitivitty Ɛ_r1 and Ɛ_r2 is connected to constant voltage U. When second dielectric is removed, intensity of electric field by inner electrode is reduced by 1/3, and electric field by outer electrode is increased two times. a=1.5mm, b=6mm, c=12mm. Calculate Ɛ_r1 and Ɛ_r2.

Result:

Ɛ_r1=6, Ɛ_r2=3

Could someone help?

Thanks for replies.
