Answer 1

$\huge\mathbb{\purple{QUESTION-}}$

A charge Q is located at the centre of a cube of edge length L. the electric flux through any face is ?

$\huge\mathbb{\purple{SOLUTION-}}$

We know that , cube has 6 faces

Let through one face electric flux is = x

therefore for 6 face electric flux is = 6x

✪$\large{\boxed{\bf \blue{\phi = \dfrac{Q}{\epsilon}}}}$

$\implies{\sf 6x=\dfrac{Q}{\epsilon}}$

$\implies{\bf \red{ x=\dfrac{Q}{6\epsilon}}}$

$\huge\mathbb{\purple{ANSWER-}}$

Electric flux through any face is ${\bf \red{\dfrac{Q}{6\epsilon}}}$
