A point charge `'q'` is placed at a distance `l'` (on th `y`-axis) vertically above the surface which lies in the `xz` plane as shown in the figure. The flux of electric field passing through the plate is

A

`q/(6epsilon_(0))`

B

`q/(18epsilon_(0))`

C

`1/(24epsilon_(0))`

D

`q/(48epsilon_(0))`

Text Solution

Verified by Experts

The correct Answer is:
C
`phi=phi_(OAB)+phi_(ABCD)`
`=q/(48epsilon_(0))+q/(48 epsilon_(0))=q/(24 epsilon_(0))`
