What are the two types of electric charges?
Think about what happens with electrons.
What does it mean that electric charge is conserved?
Consider the law of conservation in physics.
What type of charge has an excess of electrons?
Consider what happens when electrons are added.
Coulomb's Law explains the relationship between forces and what other two factors?
Think about how changing distances modifies interactions.
Two charges, +3 µC and +1 µC, are separated by a distance of 5 cm. Determine the force between them using Coulomb's law.
Convert µC to C before calculating!
A point charge of +2 µC creates an electric field at a distance of 15 cm. Compute the electric field strength.
Make sure to convert µC to C, and remember ε0 = 8.85 × 10^-12.
