Answer:
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.
