Electrostatics. The study of electric charges. What do you know about atoms?. All matter is composed of atoms We call different kinds of atoms elements Atoms form compounds Compounds have different properties, including different electrical properties. Structure of the Atom.
The study of electric charges
F = Force
k = constant, based on the medium the object is immersed in (air)
For air, the value of k = 9.0 x 109 N·m2/C2
Q = charge of each object
d = distance separating the objects
Johnny’s soccer ball has a positive charge of +6.0 x 10-6 C. Rachel’s soccer bag, with a charge of +3.0 x 10 –6 C, is 3.0 m away.
a. Calculate the force on the soccer ball.
b. Calculate the force if Rachel’s bag had a negative charge.
Q1 = 6.0 x 10-6 C
Q2 = +3.0 x 10 –6C
d = 3.0 m
k = 9.0 x 109 N·m2/C2
