Two spherical shells have a common center. The inner shell has radius R$1=5\mathrm{.}00$ cm and charge q$1=+2\mathrm{.}00106$C; the outer shell has radius R$2=15\mathrm{.}0$ cm and charge q$2=5\mathrm{.}00106$C$.$ Both charges are spread uniformly over the shell surface. Take V

$=0$ at a large distance from the shells.
