An electric field from a charge has a magnitude of 4.5 × 104 n/c at a certain location that points inward. 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; repel each other
−0.09 n; attract each other
−2.3 n; repel each other
2.3 n; attract each other

0.09 N; repel each other

Explanation:

Honestly, I do not know how this is the correct answer. If you do the proper calculations you will get -0.09 N, however when I submitted this answer it said it was incorrect. I then reset the test and picked 0.09 N; repel each other and got it correct. I truly don't know how, but I just wanted to let anyone in the future know about this :)

c.is a substance that requires a small amount of energy per gram to raise its temperature; has strong cohesive forces between molecules.

explanation:

a colorless, transparent, odorless liquid that forms the seas, lakes, rivers, and rain and is the basis of the fluids of living organisms.
