Rank the following charge/distance combinations from lowest energy to highest energy. Your answer should be a four letter "word" made up of the letters a, b, c and d. For example, if you think the order is a (lowest energy), then b, then c, then d (highest energy), you should enter the "word" abcd in the answer box. Note, the word has no spaces or commas.

a) A +2 charge and a -2 charge separated by 3 units of distance

b) A -3 charge and a -1 charge separated by 3 units of distance

c) A +1 charge and a +1 charge separated by 2 units of distance

d) A -1 charge and a +2 charge separated by 3 units of distance

a) A -3 charge and a +2 charge separated by 3 units of distance

b) A +2 charge and a +2 charge separated by 4 units of distance

c) A -3 charge and a -2 charge separated by 4 units of distance
