PS6d: In some materials, such as metals, electrons flow easily, whereas in insulating
materials such as glass they can hardly flow at all. Semiconducting materials have
intermediate behavior. At low temperatures some materials become superconductors and
offer no resistance to the flow of electrons.

OBJECTIVES
1. Calculate electric force using Coulomb’s law.
2. Compare electric force with gravitational force.
3. Apply the superposition principle to find the resultant force on a charge and
to find the position at which the net force on a charge is zero.

PS4c: The electric force is a universal force that exists between any two charged objects.
Opposite charges attract while like charges repel. The strength of the force is proportional
to the charges, and, as with gravitation, inversely proportional to the square of the
distance between them.
