6.14 A Spherical Conductor Embedded in 3 Dielectric A spherical conductor of radius R1 is surrounded by a polarizable medium which extends from R1 to R2 with dielectric constant K. (a) The conductor has charge Q. Find E everywhere and conrm that the total polarization charge is zero. (b) The conductor is grounded and the entire system is placed in a uniform electric eld E0. Find the electrostatic potential everywhere and determine how much charge is drawn up from ground to the conductor
