If a charge \(Q\) is situated at the corner of a cube, the electric flux passing through all six faces of the cube is:
1. | \(\frac{Q}{6\varepsilon_0}\) | 2. | \(\frac{Q}{8\varepsilon_0}\) |
3. | \(\frac{Q}{\varepsilon_0}\) | 4. | \(\frac{Q}{2\varepsilon_0}\) |
1. | \(\dfrac{Q}{6\varepsilon_0}\times10^{-6}\) | 2. | \(\dfrac{Q}{6\varepsilon_0}\times10^{-3}\) |
3. | \(\dfrac{Q}{2\varepsilon_0}\) | 4. | \(\dfrac{Q}{8\varepsilon_0}\) |
