Worked example
One question from this skill's own question bank, shown with its full working.
Coulombs law states that the force between two point charges is proportional to the product of the charges and
- inversely proportional to the square of the distance between them
- proportional to the distance
- independent of distance
- inversely proportional to the distance
Working: F = k q1 q2 / r squared, an inverse-square law like gravitation.
