A charge Q is placed at the comer of a cube. The electric flux through all the six faces of the cube is ?


(a) Q/3ε0

(b) Q/6ε0

(c) Q/8ε0

(d) Q/ε0


Answer :  (c) Q/8ε0




\( \Phi_E = \frac{q}{\varepsilon_0} \quad \text{(for 8 boxes)} \)


\( \Phi_E = \frac{q}{8 \varepsilon_0} \quad \text{(for 1 box)} \)
