Electric Flux: Practice Problem & Solution

Two point charge, each of q, are kept at centre of cube O and vertex A. Find \[\phi_{e}\] from shaded face. Electric Flux diagram: Two point charge, each of q, are kept
\[\frac{5q}{8\epsilon_{0}}\]
\[\frac{7}{24}\frac{q}{\epsilon_{0}}\]
\[\frac{2q}{\epsilon_{0}}\]
\[\frac{5}{24}\frac{q}{\epsilon_{0}}\]

Solution Explained:

To solve this problem, we apply the core principles of Electric Flux. Understanding the underlying formula is key to arriving at the correct answer below:

\phi= \frac{q}{6\varepsilon_{0}} + \frac{q}{24\varepsilon_{0}}= \frac{5q}{24\varepsilon_{0}}
