Thank you!

I guess I was tripped up by the wording of the question. It's asking for the sign of the charge, not the magnitude. In my head, I thought that there was no scenario in which the sphere was motionless, since same signs attract, opposite signs repel, and uncharged sphere + charged rod will result...

The force between the charges of the rod and the sphere due to the total charges on each is determined by Coulomb's law? We know that the sphere is a conductive object, which can stay electrostatically neutral in the presence of a charged rod, since it is able to become polarized. The force...

(A) incorrect, because opposite signs attract, and the sphere would've been drawn to the charged rod. (B) correct, according to the answer key, but if the charge of the sphere and the charge of the rod are the same, then wouldn't they repel each other? I'm confused as to why this is the correct...
