What is the flux through a cube of side a if a point charge of q is a one of its corner?

$fraction numerator 2 straight q over denominator straight epsilon subscript straight o end fraction$
$fraction numerator straight q over denominator 8 straight epsilon subscript straight o end fraction$
$straight q over straight epsilon subscript straight o$
$fraction numerator straight q over denominator 2 straight epsilon subscript straight o end fraction 6 a squared$

Solution

fraction numerator straight q over denominator 8 straight epsilon subscript straight o end fraction

Charge enclosed = q/8
therefore,
$flux space straight ϕ space equals space straight q subscript enclosed over straight epsilon subscript straight o straight ϕ space equals space fraction numerator straight q over denominator 8 straight epsilon subscript straight o end fraction$
