Two point charges 8 `muC` and `-8muC` are kept at points (-2cm, 0) and (2cm, 0), respectively. Calculate the electric potential at points (0, 7cm) and (4cm, 0).

Explanation

To solve the problem of calculating the electric potential at the specified points due to the two point charges, we will follow these steps:

### Given Data:
- Charge \( q_1 = 8 \, \mu C = 8 \times 10^{-6} \, C \) at point \( (-2 \, cm, 0) \)
- Charge \( q_2 = -8 \, \mu C = -8 \times 10^{-6} \, C \) at point \( (2 \, cm, 0) \)
- Point A: \( (0, 7 \, cm) \)
- Point B: \( (4 \, cm, 0) \)
