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 find the separation \( R \) between two equal charges of \( 1.0 \, \text{C} \) each, such that the electrostatic force between them 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 is given by the formula:
\[
W = m \cdot g
