Object a has a charge of negative one coulomb. At a Given distance the object with which charge would be most strongly attached by object a? - 2 C, +1 C, +2 C, -1 C

Object a, with a charge of negative one coulomb, would be most strongly attracted to an object with a charge of +2 C. The strength of the electric force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. Therefore, the object with the highest positive charge will result in the strongest attractive force with object a.
