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?

A. +1 C
B. +2 C
C. -1 C
D. -2 C

The 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, object A would be most strongly attracted to an object with a charge that has the opposite sign.

Out of the given options, the object with the charge of +1 C (option A) would be most strongly attracted by object A.
