A positive charge `+q_1` is located to the left of a negative charge `-q_2`. On a line passing through the two charges, there are two places where the total potential is zero. The reference is assumed to be at infinity.The first place is between the charge and is 4.00 cm to the left of the negative charge. The second place is 7.00 cm to the right of the negative charge. If `q_2 = -12muC and q_1 = 11 xx xmuC`, what is the value of x.

Explanation

To solve the problem, we will follow these steps:

### Step 1: Understand the Configuration
We have two charges:
- A positive charge \( q_1 = 11x \, \mu C \) located to the left of a negative charge \( q_2 = -12 \, \mu C \).
- The first point where the potential is zero is 4 cm to the left of \( q_2 \) (let's call this point A).
- The second point where the potential is zero is 7 cm to the right of \( q_2 \) (let's call this point B).
