Show on a plate the nature of variation of the (i) Electric field (ii) potenital (V), of a (small) electric dipole with the distance (r) of the filed point from the centre of the dipole.

Explanation

To show the nature of variation of the electric field (E) and potential (V) of a small electric dipole with the distance (r) from the center of the dipole, we can follow these steps:

### Step 1: Understand the Electric Dipole
An electric dipole consists of two equal and opposite charges (+q and -q) separated by a small distance (d). The dipole moment (p) is defined as:
\[ p = q \cdot d \]

### Step 2: Electric Field of a Dipole
The electric field (E) at a point along the axial line (the line extending from the positive charge to the negative charge) of a dipole at a distance r from the center of the dipole is given by:
