Section 21.1 Coulomb’s Law
If you bring two charged glass rods close together and they repel each other, what can you conclude about them?
A. Both rods have the same sign of charge.
B. The rods have opposite signs of charge.
C. One rod is charged and the other is neutral.
D. Both rods are conductors.
When an amber rod is rubbed with fur, what is the primary mechanism that causes the rod to become negatively charged?
A. The fur induces a temporary negative charge on the rod without any transfer of particles.
B. The rubbing process creates new electrons on the surface of the amber rod.
C. Electrons are transferred from the fur to the amber rod.
D. Positive charges (protons) are transferred from the amber rod to the fur.
what happens to the total mass of the amber rod and fur system after they are rubbed together?
A. The mass of the rod increases, and the mass of the fur decreases by the same amount.
B. The mass of the rod increases, while the mass of the fur stays the same.
C. The mass of both the rod and the fur remains unchanged because electrons are massless.
D. The total mass of the system decreases because energy is converted to charge.
