Electrostatics

electrostatics - study of charged particles at rest

  • electric field: the space around a charged object that can exert a force on other charged objects

EX..like a slide, the clouds,

  • electric force: a force between two charged particles, ions, or objects

q= electric charge(pos or negative either one)

E= electric field,, N/C

electric force on a charge particle in an electric field

F=qE

  • coulomb: the SI unit for electric charge (C)

2.0 × 10^4 (N/C) • 4.5 × 10^5 (C)

looking for force

F = (4.5 × 10^5 (C)) x 2.0 × 10^4 (N/C)

  • field lines: lines in a diagram that show the direction of flow of the electric field between charged particles

same charges (+)(+) (-)(-) repel each other

different charges (-)(+) attract eachother
