Two charges `-10C` and `+ 10 C` are placed 10 cm apart. Potential at the centre of the line joining the two charges is

Options

A. Zero
B. 2V
C. 3V
D. None of these

Explanation

To find the electric potential at the center of the line joining two charges, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Charges and Distance**:
- We have two charges:
- \( Q_1 = -10 \, \text{C} \) (negative charge)
- \( Q_2 = +10 \, \text{C} \) (positive charge)
