FRANCE

Charles Augustin Coulomb, in the dark blue coat with red piping and brass buttons of the Corps royal du genie. He is wearing the Croix de Saint Louis and holding his torsion balance and a paper artificially entitled "Traite de phisique [sic] et magnetisme." The medal awarded him by the Legion d'honneur rests on the table. The portrait was probably painted between and the year of his death, ; the artist is unknown.

11 Coulomb's Law Notes

1. • Charles Coulomb ( French) – Studied relationship between force and charge Coulomb’s Law • SI unit of charge = 1 coulomb (C) – NOT charge of 1 e- ( x ) – Charge of x e- • We’ll get real definition later 1 Coulomb is about how many electrons flow through a W light bulb every second.

2. • The LAW! – Force directly related to magnitude of the charges – Force inversely related to the square of the distance between the two charges Coulomb’s Law Fα q Q Fα 1 kq Q F= 2 r2 r F α qQ r2

3. • Coulomb’s Law: Should look familiar Large Magnitude 9 x N·m2/C2 Attractive or Repulsive Product of kQ q charges F= 2 r Small Magnitude Both are x N·m2/kg2 inverse-square laws GMm Product of F= r2 masses Only Attractive

4. • Sample problem 0! YEAH! – A negative charge of μC and a positive charge of 12 μC are separated by m. What is the force of attraction between the two of Coulomb’s Law them? (Remember that μ means and n means ) F= kq Q (9 x ( x (12 x ) r2 = )
