CTE Resource Center - Verso

Virginia’s CTE Resource Center

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?
