Question

a negatively charged rod is placed near two neutral metal spheres, as shown below. which statement describes the charging method shown? the spheres are charged through friction. the spheres develop the same charge. electrons move from the rod to sphere a. electrons move from sphere a to sphere b.

Explanation:

When a negatively - charged rod is placed near two neutral metal spheres in contact, due to electrostatic induction, electrons in the spheres redistribute. The negative charge on the rod repels electrons in Sphere A, causing electrons to move from Sphere A to Sphere B. There is no contact for charge transfer from the rod to the spheres, and it's not charging by friction. Also, the spheres will have opposite charges.

Answer:

Electrons move from Sphere A to Sphere B.
