Object A has a charge of -1 Coulomb. According to Coulomb's law, opposite charges attract each other. Therefore, object A would be most strongly attracted to the charge that has the largest positive value.
Among the options given:
- +1 C
- +2 C
The charge of +2 Coulombs would exert a stronger attractive force compared to the +1 Coulomb charge because the force is proportional to the product of the magnitudes of the charges.
Thus, the object with charge +2 C would be most strongly attracted by object A.
