The question is missing, however, I guess the problem is asking for the value of the force acting between the two balls.
The Coulomb force between the two balls is:
where
is the Coulomb's constant, 
is the intensity of the two charges, and 
is the distance between them.
Substituting these numbers into the equation, we get
The force is repulsive, because the charges have same sign and so they repel each other.

Answer:
Explanation:
(The following exercise is written in Spanish and for that reason explanation will be held in Spanish)
Supóngase que el planeta tiene una órbita circular, el período de rotación del planeta es:
Asimismo, la rapidez angular se describe como función de la aceleración centrípeta:
Ahora se reemplaza en la ecuación de período:
La aceleración experimentada por el planeta es:
Se reemplaza en la ecuación de período:
La distancia del planeta con respecto al sol es finalmente despejada:
Finalmente, se sustituyen las variables y se determina la distancia:
