Explanation:
You have not provided units for the distances , so they have been assumed to be in metres in the solution provided....in blue.
Always draw it first.
The force between 2 charges follows Coulomb's Law
In this case both forces on the -3C charge are repulsive forces as indicated by the green arrows
The net force, acting left to right is:
