Answer:
the correct answer is:
c) The same
Explanation:
Strictly speaking, a plastic rod weighs the same after being rubbed with fur.
Explanation:
When a plastic rod is rubbed with fur, it gains excess electrons from the fur and becomes negatively charged. However, the mass of the plastic rod remains unchanged by the transfer of electrons. Weight is a measure of the gravitational force acting on an object, which depends on the mass of the object and the gravitational acceleration. Since the mass of the plastic rod does not change when it gains excess electrons, its weight remains the same.
Therefore, the correct answer is:
c) The same
