Define electric charge in your own words.
Think about how charges interact!
What happens when two like charges are brought together?
Remember ‘Like Charges Repel’!
What is the nature of electric charge?
Consider all types of matter!
Coulomb’s Law states that force is proportional to which factors?
Remember the formula C = k * q1 * q2 / r^2!
A charge of +6 µC is placed 0.4 m away from another charge of -2 µC. Calculate the electrostatic force between them.
Focus on absolute values for the calculation, considering the nature of charges after.
Two parallel plates have an area of 0.01 m² and are separated by a distance of 0.05 m. Find the capacitance if a dielectric with a constant of 4 is used.
Break it down using the dielectric constant in your formula.
