Two equal charges are placed at a separtion of 1.0 m. What should be the magnitude of the charges so that the force between them equals of a 50 kg person?

Text Solution

AI Generated Solution

To solve the problem step-by-step, we need to find the magnitude of two equal charges placed 1 meter apart such that the electrostatic force between them equals the weight of a 50 kg person. ### Step 1: Calculate the weight of the person The weight \( W \) of a person can be calculated using the formula: \[ W = m \cdot g \] where: ...
