One cannot determine. Usually, it has a negative charge, however, in the case of bringing a positive charge near, if the object is neutral, it will still be attracted. In the case of conductors, electrons will move closer to the + charge, making the net force attractive, as the electrons are closer than the remaining positive charges.
It cannot be determined from attraction alone.
