The Coulomb force between two small, identical metallic balls, carrying charges q1 and q2, respectively, is found to be an attraction of 2.00 N when they are 1.00 m apart. The force becomes a repulsion of 1.00 N after the balls are brought in contact and placed back to their original positions. What are the values of q1 and q2 if q1<0 and |q1|<|q2|.
