Question

Two charged objects are separated by some distance. the charge on the first object is greater than the charge on the second object. how does the force between the two objects compare?

Answer 1

Force will be compared by coulomb law


M12 = M21

Answer 2

The forces in both directions are equal. Their strength depends on the PRODUCT of the charges, not on their individual values or the comparison between them. Same goes for gravity. Your weight on Earth is exactly the same as the Earth's weight on YOU.
