Two charges `+20 muC and -20 muC` are held `1 cm` apart. Calculate the electric field at a point on the equatorial line at a distance of `50 cm` from the center of the dipole.

Explanation

To solve the problem of finding the electric field at a point on the equatorial line of a dipole formed by two charges of +20 µC and -20 µC held 1 cm apart, we can follow these steps:

### Step 1: Understand the Dipole
A dipole consists of two equal and opposite charges separated by a distance. Here, we have:
- Charge \( q_1 = +20 \, \mu C = +20 \times 10^{-6} \, C \)
- Charge \( q_2 = -20 \, \mu C = -20 \times 10^{-6} \, C \)
- Separation distance \( l = 1 \, cm = 0.01 \, m \)
