Which French scientist (1736 -1806) is best known for his law of electrostatic force and gives his name to the unit of electric charge ?
Charles-Augustin de Coulomb He thought that the attraction and repulsion were due to different kinds of fluids. Charles-Augustin de Coulomb Charles-Augustin de Coulomb (; ; 14 June 1736 – 23 August 1806) was a French military engineer and physicist. He is best known for developing what is now known as Coulomb's law, the description of the electrostatic force of attraction and repulsion, but also did important work on friction. The SI unit of electric charge, the coulomb, was named in his honour in 1908. Charles-Augustin de Coulomb was born in Angoulême, Angoumois county, France, to Henry Coulomb, an inspector of the royal demesne
Electrostatic induction field directed from point formula_1 to point formula_2 then it will exert a force on a charge moving from formula_2 to formula_1. Work will have to be done on the charge by a force to make it move to formula_1 against the opposing force of the electric field. Thus the electrostatic potential energy of the charge will increase. So the potential at point formula_1 is higher than at point formula_2. The electric field formula_8 at any point is the gradient (rate of change) of the electrostatic potential formula_9 : Since there can be no electric field inside a conductive object
