Question

When moving electron comes closer to other stationary electron, then its kinetic energy and potential energy respectively _____ and _____.

• A. Increases, increases
• B. Increases, decreases
• C. Decreases, increases
• D. Decreases, decreases

Answer 1

The correct option is C Decreases, increases

When electron comes closer to the other stationary electron, its kinetic energy decreases because of repulsion between them. As per conservation of energy, the potential energy increases.
