Question

Find the electric flux through each of the six cube faces $S_1,S_2,S_3,S_4,S_5$ and $S_6$

Answer 1

${\phi }_{s1}=-E_y{l}^2=-C{l}^2$,
${\phi }_{s2}=E_z{l}^2=-D{L}^2$,
${\phi }_{s3}=E_y{l}^2=C{L}^2$,
${\phi }_{s4}=-E_z{l}^2=D{L}^2$,
${\phi }_{s5}=E_x{l}^2=-B{L}^2$,
${\phi }_{s6}=-E_x{l}^2=B{L}^2$
