Assume e=e. if e is not given Two concentric spherical cells of the radii rs= 1 cm and r(2) =2.5 cm have uniform surface charge densities ps1 c/m and ps2
c/m respectively the region 0r2 The electrical potential at r=0 The relationship between ps1 and ps2 so thst E=0 outside of r+r1 V at the surface r=r2 for the case described in c
