In Figure a semi-infinite non-conducting rod (that is, infinite in one direction only) has uniform linear charge

Question:

In Figure a "semi-infinite" non-conducting rod (that is, infinite in one direction only) has uniform linear charge density λ, Show that the electric field Ep at point P makes an angle of 45o with the rod and that this result is independent of the distance R.
