–1 C

Answer 1

The object with a charge of +1 Coulomb would be most strongly attracted by object A which has a charge of -1 Coulomb.

Answer 2

k Q2 Q2 / r^2
so +2
1*2 > 1*1

Answer 3

Yes, you are correct. According to the formula for electrical force, F = k * (Q1 * Q2) / r^2, where k is the electrostatic constant, Q1 and Q2 are the charges, and r is the distance between the charges.

If we compare the attractive force between object A with a charge of -1 Coulomb and an object with a charge of +2 Coulombs (Q2), to the attractive force between object A and an object with a charge of +1 Coulomb (Q2), the force between A and the +2 Coulomb object would be stronger.

Since 1*2 (Q1 * Q2) is greater than 1*1, the object with a charge of +2 Coulombs would be more strongly attracted to object A.
