An electric field from a charge has a magnitude of 4.5 × 104 N/C at a certain location that points outward. If another charge with a magnitude of −2.0 × 10−6 C is brought near it, what is the strength of the electrostatic force that acts on this charge and how do the two charges behave?

−0.09 N; attract each other
−2.3 N; repel each other
2.3 N; attract each other
