3. Coulomb's Law states that the attraction force between two charges is proportional to the product of charges and inversely proportional to the distance between the two charges. If two particles of charge q = 1 unit are located at x = 0 and x = 2, a particl with charge (.1 = 1 located at x experiences the force I: k F= , x2+(2x)2 where k is a positive constant. Sketch the graph of the net force function. Interpret the graph by elaborating on What happens to the force when x varies
