Positive work is done on a system of two equal charges by an outside agent to bring both the charges together from infinite separation. Can the polarities of charges be determined from this fact?

Explanation

To determine whether the polarities of the charges can be identified from the fact that positive work is done to bring two equal charges together from infinite separation, we can analyze the situation step by step.

### Step-by-Step Solution:

1. **Understanding the Charges**: We have two equal charges. Let's denote them as \( Q_1 \) and \( Q_2 \). Since they are equal, we can say \( Q_1 = Q_2 = Q \).

2. **Identifying the Nature of Work Done**: The question states that positive work is done on the system by an outside agent. This means that energy is being supplied to the system to move the charges closer together.
