Coulomb's Law
Torsion Balance
An instrument used to measure minute forces such as electrostatic or magnetic attraction and repulsion.
Charles-Augustin De Coulomb
A well-renowned 18th-century French physicist.
Coulomb's Law
A fundamental law of electromagnetism and publish it in 1785.
Coulomb’s Law quantifies the force of electric attraction or repulsion between two electrically charged objects.
It states:
The electrostatic force between two charged objects is directly proportional to the product of the quantity of charge on the objects and inversely proportional to the square of the separation distance between the two objects.
The magnitude of the electrostatic force is equal to Coulomb's constant multiplied by the absolute value of the charge of each object divided by the distance between the centre of both the objects squared.
