The correct Answer is:
` 0`
We can consider charges of `AD, EB, CF` as a diple . Now the line passing through `O` and perpendicular to the plane will act like an equitorial line .

Let point `P` at distance `x` from `O`. Field at `P` will be vector sum of field due to three dipoles
`vec E_P = vec E_(AD) + vec E_(BF) _ vec E_(CF)`
`E_P =0`
