$100 Charging • To create a positive ion you must ______?

$100 Answer Charging • Decrease the number of electrons.

$200 Charging • Describe in detail why a balloon sticks to a wall after rubbing in on your head.

$200 Answer Charging • The negative charge one the balloon induces an electric dipole on the wall moving the like negative charges in the wall further from the balloon than the positive charges. This allows the balloon to stick.

$300 Charging • What are the three types of charging? Give a description and an example of each.

$300 Answer Charging • Friction, Contact, Induction

$400 Charging • What is the force between two particles with charges of 2.4 x 10^-7 C and a distance of .4 meters?

$400 Answer Charging • .00324 N

$500 Charging What is the force between a 3.5 x 10^-8 C Negative charge and a 4.2 x 10^-7 C Positive Charge with a separation of .6m? Is this an attractive force or a repulsive force?

$500 Answer Charging • -3.675 x 10 ^ -4 N Attractive Force
