What will be the total flux through the faces of the cube as given in the figure with a side of length 'a' if a charge q is placed at?
Match the following:
| Column I | Column II | ||
| (a) | a corner of the cube | (i) | \(\phi=\dfrac{q}{2\epsilon_0}\) |
| (b) | mid-point of an edge of the cube | (ii) | \(\phi=\dfrac{q}{8\epsilon_0}\) |
| (c) | centre of a face of the cube | (iii) | \(\phi=\dfrac{q}{2\epsilon_0}\) |
| (d) | mid-point of B and C | (iv) | \(\phi=\dfrac{q}{4\epsilon_0}\) |
| 1. | (A)\(\rightarrow \)(iv), (B)\(\rightarrow \)(ii), (C)\(\rightarrow \)(iii), (D)\(\rightarrow \)(i) |
| 2. | (A)\(\rightarrow \)(ii), (B)\(\rightarrow \)(iv), (C)\(\rightarrow \)(i), (D)\(\rightarrow \)(iii) |
| 3. | (A)\(\rightarrow \)(iii), (B)\(\rightarrow \)(ii), (C)\(\rightarrow \)(iv), (D)\(\rightarrow \)(i) |
| 4. | (A)\(\rightarrow \)(i), (B)\(\rightarrow \)(iii), (C)\(\rightarrow \)(ii), (D)\(\rightarrow \)(iv) |
