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? ( -1C ; -2C; +1C; +1C )

To determine which object would be most strongly attracted to object A, which has a charge of -1 Coulomb, we should consider the nature of electric charges.

1. Like charges repel each other (e.g., negative repels negative).
2. Opposite charges attract each other (e.g., negative attracts positive).

Given the options:

• -1C (repels)
• -2C (repels)
• +1C (attracts)
• +2C (not listed, but would also attract)

Among these options, both -1C and -2C would be repelled by the -1C charge of object A. The only charge that would be attracted to object A is +1C.

Since object A (with -1C) attracts +1C and repels -1C and -2C, the object that would be most strongly attracted by object A is +1C.

The force of attraction will also be stronger with larger positive charges if they were listed. However, given the options, +1C is the most suitable answer.
