Find out potential energy of the two point charge system having charges `q_(1)` and `q_(2)` separated by distance r.

Explanation

To find the potential energy of a two-point charge system with charges \( q_1 \) and \( q_2 \) separated by a distance \( r \), we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the System**: We have two point charges, \( q_1 \) and \( q_2 \), separated by a distance \( r \). The potential energy \( U \) of the system is related to the work done in bringing these charges from infinity to their positions.

2. **Initial Condition**: Initially, we assume that both charges are at a very large separation (effectively at infinity). At this point, the potential energy is zero because the electrostatic force between them is negligible.
