In the above diagram a neutral rectangular conducting slab lies between four infinite

sheets of charge where o $=1\mathrm{.}3$ C$/$m$?.$ The faces of the conductor parallel to the infinite

sheets are also infinite.

$9,$ What is the magnitude of the electric field inside the conductor?

A$.75$ V$/$m B$.150$ V$/$m C$.300$ V$/$m D$.600$ V$/$m E$.1200$ V$/$m AB$.0$ V$/$m

$10.$ What is the surface charge density o of the leftmost face $($see the above figure$)$ of the conducting slab?
