Scientists experimenting with two charged objects of 2.56 x 10-6 C and 3.34 x 10-7 C displayed a repulsion of 2.26 x 10-3 N. How far apart were the two charged objects during the experiment to the nearest tenth of a meter?

The objects were 1.8m apart.

Explanation:

We will start stating the Coulomb's Law. It says that:

Where F_e is the electric force between the objects, q_1 and q_2 are the magnitude of the charge of the objects, r is the distance between them and K is the Coulomb's constant ( in vacuum). Solving for the distance r we have:

Plugging the given values into this equation, we obtain:

In words, the two charged objects were 1.8m apart.
