Object A has a charge of –1 Coulomb. At a given distance, the object with which charge would be most strongly attracted by object A?
–2 C
+2 C
–1 C
+1 C
Object A has a charge of –1 Coulomb. According to Coulomb's law, objects with opposite charges attract each other with a force that is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
Therefore, object A would be most strongly attracted to an object with a charge of +2 C, as the product of their charges would result in a large attractive force. The other options (+1 C, -1 C, and -2 C) would also result in attractive forces, but they would be weaker compared to the attraction between object A (-1 C) and the object with a charge of +2 C.
