4 cards from this section. Quick, good the night before a test.
Define electric charge.
Think about the interaction of charged objects.
What are the two types of electric charges?
Remember how they affect each other's movement.
What does Coulomb's law pertain to?
Consider what forces occur in electrostatics.
Is electric charge conserved in a closed system?
Remember the principle related to charge creation and annihilation.
Two charges, +2 μC and -6 μC, are placed 0.5 m apart. Calculate the force acting between them and indicate its nature (attractive or repulsive).
First identify the charge types and signs before substituting into the formula.
Explain how a dipole interacts with an external electric field, including formulas for dipole moment and field.
Remember that torque formula also plays a role here!
