For Question 1, the correct answer is:

**a. Electrons are added to the rod.**

When a rubber rod is rubbed with fur, electrons are transferred from the fur to the rubber rod, giving the rod a negative charge.

For Question 2, the correct answer is:

**b. charges are of like signs.**

A repelling force occurs between two charged objects when both objects have the same type of charge (either both positive or both negative).
