A metallic spherical shell of radius r1 ...

A metallic spherical shell of radius `r_1` is surrounded by another concentric metallic spherical shell of radius `r_2`. The space between the two shells is filled with a dielectric of dielectric constant K. If a charge Q is given to the inner shell, the charge appearing on the outer surface of the outer shell is

`+Q`

`(+Qr_1^2)/r_2^2`

`(+QKr_1^2)/r_2^2`

`Q[1-1/K]`
