Some work is done to move a charge Q from infinity to a point A in space. The potential of the point A is given as V. What is the work done to move this charge from infinity in terms of Q and V?

Explanation

To solve the problem of calculating the work done to move a charge \( Q \) from infinity to a point \( A \) in space where the potential is \( V \), we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Electric Potential**:
The electric potential \( V \) at a point in space is defined as the work done per unit charge in bringing a charge from infinity to that point.

2. **Identifying the Work Done**:
