Point charges of 9 `muC and -6muC` are placed at a distance of 90 cm from each other. How many points can you find on line joining the charges where electric potential is zero? At what distance these these points are located from 9 `muC`?

Explanation

To solve the problem of finding the points where the electric potential is zero between two point charges, we can follow these steps:

### Step 1: Understand the Configuration
We have two point charges:
- \( Q_1 = 9 \, \mu C \) (positive charge)
- \( Q_2 = -6 \, \mu C \) (negative charge)

These charges are placed 90 cm apart.
