Question
A cube of side a encloses a point charge q at its
center. What is the electric flux through one of its faces?Solution
According to Gauss’s Law , the total electric flux through a closed surface enclosing a net charge Φtotal = q / ε0 In this case:
- A point charge q is placed at the center of a cube .
- The cube has 6 identical faces , and due to symmetry, the flux is equally distributed through all faces.
