A charge Q is placed at the centre of a cube of sides a. The total flux of electric field through the six surfaces of the cube is
- A$$ \frac{6 \mathrm{Qa}^2}{\epsilon_0} $$
- B$$ \frac{\mathrm{Q} \mathrm{a}^2}{6 \epsilon_0} $$
- C$$ \mathrm{Q} / \epsilon_0 $$
- D$$ \mathrm{Q} \mathrm{a}^2 / \epsilon_0 $$
