What is the angle between the directions of electric field at any (i) axial point and
` (ii) equatorial point due to an electric dipole ?`

Explanation

The directions of electric field `vecE_(1)` at axial point `P_(1)` and electric field `vecE_(2)` at equatorialpoint `P_(2)` are shown in fig. Obvioulsy, angle between `vecE_(1)` and `vecE_(2)` is `180^o`.
