When a plastic ball is rubbed with fur, the plastic ball attracts a positively charged pith ball. when a glass rod is rubbed with fur, the glass rod repels the same pith ball. based on these two observations, which of these will most likely gain electrons more readily? a) fur b) glass c) plastic d) plastic and glass

C) plastic

Explanation:

We know that like charges repel each other and unlike charges attract each other. When plastic ball is rubbed with fur, it could attract a positively charged pith ball. This means that the plastic ball gained electrons from the fur and became negatively charged.

When a glass rod is rubbed with fur, it could repel the same positively charged pith ball. This means glass rod lost electrons to the fur and became positively charged.

From this, we can conclude that most likely plastic could readily gain electrons.
