1. The problem statement, all variables and given/known data Below are seven arrangements of two electric charges. All of the charges are the same size, 20 C, but they are either positive or negative. Each figure also has a point labeled P that lies on a straight line with the two charges. The distance between any two items is all 5 cm. There are no other charges in this region. A +5 C charge is placed at point P. Rank the strength (magnitude only) of the electric force on the +5 C charge when it is placed at point P from greatest to least. 2. Relevant equations Fe= k(q1q2)/r^2 3. The attempt at a solution help get me started please? :) I don't know how to get started.
