# CTE Resource Center - Verso - Electronics Systems I Task 1176103429

# Describe the law of charges.

## Definition

Description should include
• explaining that between magnetic objects, those with like charges repel and those with unlike charges attract
• knowing that the size of the charge and the amount of force produced have a direct relationship
• understanding that force is applied in a direct line between objects
• identifying that the inverse square law of the electrostatic follows the force of attraction
• explaining that the electrostatic force of attraction between two point charges are proportional to the product of the magnitudes.

## Process/Skill Questions

• Who is credited with discovering the law of charges?
• How should objects with similar charges behave with each other, according to the law of charges?
• What are some everyday examples of the law of charges?
• How does the size of a magnetic field relate to charge?
