As a positively charged object moves toward a negatively charged object, their potential energy increases. As a positively charged object moves toward another positively charged object, their potential energy increases. As a negatively charged object moves toward another negatively charged object, their potential energy increases. Increasing the distance between two electrically charged objects may raise or lower their potential energy. All of the above are true.

As a positively charged object moves toward another positively charged object, their potential energy increases. True

As a negatively charged object moves toward another negatively charged object, their potential energy increases True

Explanation:

When two like charges move towards each other, there is increase in potential energy because the motion is in opposition to the direction if the field. Hence when two negative or two positive charges move towards each other, there is an increase in potential energy.

However, potential energy is inversely related to the distance of separation of the charges.
