A charge q is located at the centre of a cube. The electric flux through any face is ?

(a) \( \frac{q}{6(4\pi\varepsilon_0)} \)

(b) \( \frac{2\pi q}{6(4\pi\varepsilon_0)} \)

(c) \( \frac{4\pi q}{6(4\pi\varepsilon_0)} \)

(d) \( \frac{\pi q}{6(4\pi\varepsilon_0)} \)

Answer :  (c) \( \frac{4\pi q}{6(4\pi\varepsilon_0)} \)
