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. -2c b. -1c C. +1c d. +2c

The object with which charge would be most strongly attracted by object a would be an object with a charge opposite in sign to object a's charge. So, in this case, the object with a charge of +1 coulomb (option C) would be most strongly attracted by object a with a charge of -1 coulomb.
