Week 5- The inverse square law
Objectives: 1. understand the concept of the inverse square law Source: Google Who discovered the inverse square law? Robert Hooke and the Inverse Square Law. there is a claim that Robert Hooke discovered an inverse square relation of gravitating bodied prior Isaac Newton , who later applied it more successfully in astronomy ( Hooke apparently studied bodies on earth Why is Coulomb law called an inverse square law? The law . Coulomb's law states that: The magnitude of the electrostatic force of attraction between two point charges is directly proportional to the product of the magnitudes of charges and inversely proportional to the square of the distance between them. The force is along the straight line joining them. What is r in Coulomb's law? The distance between the two charges is " r ." The " r " actually stands for "radius of separation" but you just need to know i...
