a positive rod is placed to the left of sphere a, and the spheres are separated. which best describes the spheres? sphere a is negative and sphere b is positive because protons from sphere a are attracted to the rod and move to sphere b. sphere a is negative and sphere b is positive because electrons from sphere b are attracted to the rod and move to sphere a. sphere a is positive and sphere b is negative because electrons from the rod move to sphere b and protons then move to sphere a. sphere a is positive and sphere b is negative because protons move from sphere b to the rod and also to sphere a.

a positive rod is placed to the left of sphere a, and the spheres are separated. which best describes the spheres? sphere a is negative and sphere b is positive because protons from sphere a are attracted to the rod and move to sphere b. sphere a is negative and sphere b is positive because electrons from sphere b are attracted to the rod and move to sphere a. sphere a is positive and sphere b is negative because electrons from the rod move to sphere b and protons then move to sphere a. sphere a is positive and sphere b is negative because protons move from sphere b to the rod and also to sphere a.

Answer

Brief Explanations:

Protons are in the nucleus and do not move freely in electro - static induction. Only electrons can move. When a positive rod is placed near the neutral spheres, electrons are attracted to the positive rod. So electrons from sphere B move to sphere A. Sphere A gains electrons and becomes negative, while sphere B loses electrons and becomes positive.

Answer:

Sphere A is negative and sphere B is positive because electrons from sphere B are attracted to the rod and move to sphere A.
