2 cards from this section. Quick, good the night before a test.
What happens when two like charges are brought close together?
Think about the interaction of magnets.
State Coulomb's law in simple terms.
Recall the variables related to distance and magnitude.
What law describes the force between two point charges?
Think of the law named after a French physicist.
Forces in an electrostatic situation can be calculated by considering each force individually regardless of other charges present.
Consider how you gather forces similarly in physics.
Consider three charges placed in a line. Charge A is 2μC, B is -3μC, and C is 5μC. Calculate the net force on charge C due to A and B.
Don't forget to consider the directions when computing net force.
If a charge Q at rest begins to move in an electric field E, how does the force acting on it change?
Think about how forces can alter with movement within a field.
