Two point charges are brought closer together, increasing the force between them by a factor of 22. by what factor did their separation decrease? hint: if the force increases, distance between charges must decrease. force is indirectly proportional to the distance squared.

In a given chemical reaction, the energy of the products is greater than the energy of the reactants. which statement is true for this reaction?
