Answer:
2.30 × 10⁻⁸ N if the two electrons are in a vacuum.
Explanation:
The Coulomb's Law gives the size of the electrostatic force between two charged objects:
,
where
For the two electrons:
The sign of is negative. In other words, the two electrons repel each other since the signs of their charges are the same.
