Select the correct answer. Two charged objects, A and B, exert an electric force on each other. What happens if the distance between them is increased? OA The charge on B decreases. OB The charge on B increases. OC The electric force between them decreases. OD. The electric force between them increases.

OC The electric force between them decreases.

Explanation:

Electric force is a force due to charges which charged objects exert on each other. The charged objects A and B thus exert a definite force on each other which its value can be varied by varying the distance between them.

It is goo to note that the force between two charges is inversely proportional the the square of the distance between them. Thus when the distance is increased, the electric force would decease.

In the given question, option C is appropriate.

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
