A cubical region of side a has its centre at the origin. It encloses three fixed point charges, -q at (0, -a/4, 0), +3q at (0, 0, 0) and -q at (0, +a/4 ,0).
Match the following :
| List I | List II |
| P) The net electric flux crossing the plane x = +a/2 is equal to | i) the net electric flux crossing the plane y = -a/2 |
| Q) The net electric crossing the plane y = +a/2 is more than the net electric flux crossing the plane y = -a/2 | ii) the net electric flux crossing the plane x = -a/2 |
| R) The net electric flux crossing the entire region is | iii) the net electric flux crossing the plane x = +a/2 |
| S) The net electric flux crossing the plane z = +a/ 2 is equal to | iv) \( \frac { q }{ { \varepsilon }_{ o } } \) |
