Two black rectangular surfaces $1$ m x $2$ m are parallel and oppositely facing each other. The two surfaces are placed $2$ m apart. If surface $1$ is at $107$C and surface $2$ is at $307$C$,$ determine the net rate of energy loss from the surface at $107$C if the surrounding other than the two surfaces behaves as a black body and it is at $($i$)-$

$273$C and $($b$)27$C
