What is Coulomb's Law?
Think about how two charges interact with each other.
What happens when two positive charges are brought close together?
Recall the nature of like charges.
What is the relationship between force and distance in Coulomb's Law?
Recall the formula.
True or False: Like charges attract.
Remember the nature of electric charges.
Two charges of +5 µC and -5 µC are placed 50 cm apart. Calculate the electric force between them.
Pay attention to the sign of the charges.
A charge of +3 µC exerts a force of 0.12 N on a second charge placed in its vicinity. What could the second charge be?
You may need to calculate the force acting at different distances.
