"Coulomb's law gives the magnitude of the force between two point charges. It states that the force is proportional to the product of the charges and inversely proportional to the square of the distance between them: F = k|q₁q₂|/r²."

What you'll learn
- State Coulomb's Law in words and mathematical form
- Calculate the magnitude of the electric force between two point charges
- Determine the direction of the electric force between charges using sign conventions
- Compare the electric force to the gravitational force — identifying similarities in form and key differences in magnitude and sign
- Apply superposition to find the net electric force on a charge due to multiple other charges
