At what separation should two equal charges 1.0 C each, be placed so that the force between them equals the weight of a 50 kg person?

Explanation

To solve the problem, we need to determine the separation \( r \) at which the electrostatic force between two equal charges of \( 1.0 \, \text{C} \) each equals the weight of a \( 50 \, \text{kg} \) person.

### Step-by-Step Solution:

1. **Calculate the Weight of the Person**:
The weight \( W \) of a person can be calculated using the formula:
\[
W = m \cdot g
