a 7.0 pF spherical capacitor consists of an inner conducting sphere of radius Rin=R and an- outer conductor with spherical Wall of Radius Rout=2R. The space between is filled with a dielectric material of permittivity ɛ1=5.3ɛ0. Then inner material is replaced by another dielectric material of permittivity ɛ2=1.9ɛ0. To keep the capacitance as 7.0 pF, the Radius of the inner conductor is changed to R2 while the Radius of outer conducting sphere is remained unchanged. What is the new Radius R2 in mm?
