    PROBLEM \(\PageIndex{1}\)

    Would you expect two like charges close together to have a relative potential energy above or below 0?

    Answer

    Like charges should have energies above 0.

    PROBLEM \(\PageIndex{2}\)

    Would you expect two like charges far apart to have a relative potential energy above or below 0?

    Answer

    Like charges should have energies above 0.

    PROBLEM \(\PageIndex{3}\)

    Would you expect two opposite charges far apart to have a relative potential energy above or below 0?

    Answer

    opposite charges should have energies below 0.

    PROBLEM \(\PageIndex{4}\)

    Rank the following scenarios from HIGHEST (most positive) to LOWEST (most negative) relative potential energy.

    a. +3, -2 charges, 100 angstroms apart

    b. +1, -1 charges, 200 angstroms apart

    c. +1, +1 charges, 200 angstroms apart

    d. -3, -3 charges, 100 angstroms apart

    Answer

    d, c, b, a
