A charge \(q\) is placed at the centre of a cube. The electric flux passing through the cube is
- A \(\frac{1}{3} \frac{q}{\varepsilon_{0}}\)
- B \(\frac{1}{6} \frac{q}{\varepsilon_{0}}\)
- C \(\frac{q}{\varepsilon_{0}}\)
- D \(\frac{1}{4} \frac{q}{\varepsilon_{0}}\)
Answer & Solution
Correct Answer
(C) \(\frac{q}{\varepsilon_{0}}\)
Step-by-step Solution
Detailed explanation
According to Gauss's law, total electric flux passing through the cube, \(\phi=\frac{\text { total enclosed charge }}{\varepsilon_{0}}=\frac{q}{\varepsilon_{0}}\)
