Question

A charge $Q$ is kept at the corner of a cube. Electric flux passing through one of those faces not touching that charge is

• A. $\frac{Q}{24{\epsilon }_0}$
• B. $\frac{Q}{3{\epsilon }_0}$
• C. $\frac{Q}{8{\epsilon }_0}$
• D. $\frac{Q}{6{\epsilon }_0}$

Answer 1

Answer: (A)

${\varphi }_{\text{Net }}=\frac{q}{8{\epsilon }_0}$ (Of $3$ surface)
${\varphi }_{\text{One surface }}=\frac{q}{24{\epsilon }_0}$
