How does the electrostatic potential energy (PE) change as an electron and proton get farther from each other? When two electrons get farther apart? Why? ?− and ?+ get farther      ?− and ?− get farther     Reasoning A) PE increases (↑) PE increases (↑) Potential energy always increases when the distance between objects increases. B) PE increases (↑) PE decreases (↓) As distance increases, electrostatic PE increases (↑) between repulsive objects & decreases (↓) between attractive objects. C) PE increases (↑) PE decreases (↓)  As distance increases, electrostatic PE increases (↑) between attractive objects & decreases (↓) between repulsive objects. D) PE decreases (↓) PE increases (↑) As distance increases, electrostatic PE decreases (↓) between attractive objects & increases (↑) between repulsive objects. E) PE decreases (↓) PE increases (↑) As distance increases, electrostatic PE decreases (↓) between repulsive objects & increases (↑) between attractive objects.  (Sorry about the spacing)

A) PE increases (↑) PE increases (↑)

Potential energy always increases when the distance between objects increases.

B) PE increases (↑) PE decreases (↓) As distance increases, electrostatic PE increases (↑)
between repulsive objects & decreases (↓) between attractive objects.

C) PE increases (↑) PE decreases (↓) 

As distance increases, electrostatic PE increases (↑) between attractive objects & decreases (↓) between repulsive objects.

D) PE decreases (↓) PE increases (↑)
As distance increases, electrostatic PE decreases (↓) between attractive objects & increases (↑) between repulsive objects.

E) PE decreases (↓) PE increases (↑)
As distance increases, electrostatic PE decreases (↓) between repulsive objects & increases (↑) between attractive objects.
