Calculate the electric field intensity due to an electric dipole of length 10 cm having charges of `100 muC` at a point 20 cm from each charge on equatorial line.

Explanation

To calculate the electric field intensity due to an electric dipole at a point on the equatorial line, we can follow these steps:

### Given:
- Length of the dipole, \( l = 10 \, \text{cm} = 0.1 \, \text{m} \)
- Charge of each dipole, \( Q = 100 \, \mu\text{C} = 100 \times 10^{-6} \, \text{C} \)
- Distance from each charge to the point on the equatorial line, \( d = 20 \, \text{cm} = 0.2 \, \text{m} \)

### Step 1: Calculate the dipole moment \( p \)
