C) the force is 1/9 as great
The force between two equally charged objects is inversely proportional to the square of the distance between them. So, if the distance between the objects triples, the force will decrease by a factor of 3 squared, which is 9. Therefore, the force between them will be 1/9 as great.
imagine two equally charged objects that are hanging a certain distance from one another. How does the force between them change if the distance between them triples?
A) the force becomes 3x’s greater
B) the force becomes 9x’s greater
C) the force is 1/9 as great
D) the force is 1/3 as great
