Be able to explain the distribution of charge on the surface of conductors and insulators. Charges evenly distribute on the surface of a conductor Charges are restricted from moving on the surface of a insulators and will remain in one location the electric force between two charges separated by a Coulomb’s Law (describes certain distance) Should be able to explain the principles related to torsion Coulomb’s balance experiment and compare it to experiment Cavendish’s (use absolute values in this formula) Graphs showing relationship between force electric and distance Compare law to universal law of gravitation in terms Coulomb’s Newton’s of the inverse square relationship Should be able to draw a free-body diagram and solve for any of the missing forces or angles Need to be able to calculate the net electrical force on one charge due to two other charges (remember directions)!
