A charge `2 muC` is taken from inifinity point in an electric field, without changing its velocity. If work done against eletrostatic forces is `-40 mu J`, then find the potential at that point.

Explanation

To solve the problem step by step, we need to find the electric potential at a point in an electric field where a charge of 2 µC is brought from infinity, and the work done against electrostatic forces is -40 µJ.

### Step-by-Step Solution:

1. **Understand the Given Information:**
- Charge, \( Q = 2 \, \mu C = 2 \times 10^{-6} \, C \)
- Work done against electrostatic forces, \( W = -40 \, \mu J = -40 \times 10^{-6} \, J \)
