Gauss' Law

Concept #1: Coulomb's Law

Practice: If the force between two charges is F when the distance is d, what will the force between the two charges be if they were moved to a distance of 2d?

Example #1: Charges In A Line (Find Zero Force)

Practice: In which direction will the −1 C charge move? If it has a mass of 10 g, what will its initial acceleration be? Example #2: Charges In A Triangle (Rank Force Pairs)

Example #3: Charges in a Plane

Example #4: Exploiting Symmetry

Practice: What is the direction of the net force on the charge at the center of the square in the following figure? Example #5: Electroscope (Find Charge)
