Hurry ! a negatively charged rod is placed near two neutral metal spheres, as shown below. which statements describe the charging method shown? check all that apply. a.) the spheres develop opposite charges. b.) the spheres develop the same charge. c.) electrons move from the rod to sphere a. d.) electrons move from sphere a to sphere b. e.) the spheres are charged through conduction. f.) the spheres are charged through friction. g.) the spheres are charged through induction.

A.) The spheres develop opposite charges.

D.) Electrons move from sphere A to sphere B.

E.) The spheres are charged through conduction.

Explanation:

In the diagram, spheres A and B are in contact, so this method is charging by contact or conduction. The rod is negatively charged, thus it attracts the protons in A and repels it electrons. Which flow into sphere B when earthened, so that B becomes negatively charged. On separation of the spheres and then removal of the charged rod, sphere A would be positively charged. Thus spheres A and B possess opposite charges.
