Since both pith balls have a negative charge, there will be a repulsive electric force between them, pushing them away from each other.
Since both pith balls have a negative charge, there will be a repulsive electric force between them, pushing them away from each other.

The greater the distance between the pith balls, the negative charges and electric force between them become less.
The greater the distance between the pith balls, the negative charges and electric force between them become less.

The greater the distance between the pith balls, the greater the negative charges and the greater the electric force between them.
The greater the distance between the pith balls, the greater the negative charges and the greater the electric force between them.

Since both pith balls have a negative charge, there will be an attractive electric force between them, pulling them together.

Answer 1

The correct options that describe what is happening between the two pith balls that each have negative charges are:

1. **Since both pith balls have a negative charge, there will be a repulsive electric force between them, pushing them away from each other.**

2. **The greater the distance between the pith balls, the electric force between them becomes less.**

The reasoning is as follows:

- Like charges repel each other, which is why the negative charges on the pith balls cause them to push away from one another.

- The electric force between two charged objects decreases with an increase in distance, according to Coulomb's law.
