How does position affect energy transfer to the objects in system A/B?

Pick TWO!

• When two like charged objects are closely positioned, potential energy increases.

• When two like charged objects are closely positioned, potential energy decreases.

• When the distance between two like charged objects increases, potential energy increases.

• When the distance between two like charged objects increases, potential energy decreases.
