Charles-Augustin de coulomb

invention

• he invented the torsion balance which allowed him to
• to measure really small charges, & expiramentally estimate
• the force of attraction or repulsion between 2 objects.
• The data he gathered from his invention allowed him
• to formulate his law- Coulombs law.

Coulomb's Law

• Coulomb's law states that the interaction between
• charged objects is non-contact force that actions over some 
• distance of separation. Every electrical interaction involves
• a force that highlights these 3 variables: charge, charge,
• and distance. There is always 2 charges and a distance between objects.

Background

• Was born in France, went to school
• in Paris. He came from a wealthy and well
• known family. He studied language, literature
• and philosophy.
