Two point charges of `5 mu C` and `20 mu C` are separated by a distance of 2m. Find the point on the line joining them at which electric field intensity is zero.

Explanation

To find the point on the line joining two point charges where the electric field intensity is zero, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Charges and Their Positions:**
- Let charge \( Q_1 = 5 \, \mu C \) be at point A.
- Let charge \( Q_2 = 20 \, \mu C \) be at point B.
- The distance between the two charges is given as \( d = 2 \, m \).
