A point charge +q is placed at mid point of a cube of side ’L’. The electric flux emerging from the cube is ?

A point charge +q is placed at mid point of a cube of side ’L’. The electric flux emerging from the cube is ?

(a) \(\frac{q}{\varepsilon_0}\)
(b) \(\frac{6qL^2}{\varepsilon_0}\)
(c) \(\frac{q}{6L^2\varepsilon_0}\)
(d) zero

Answer :  (a) \(\frac{q}{\varepsilon_0}\)

\( \Phi_E = \frac{Q_{\text{enc}}}{\varepsilon_0} \)
