Two conductive, uncharged spheres are touching each other on an insulated table. A positively charged nonconductive rod is brought in the vicinity of sphere A, not touching it, and then the spheres are separated. Sphere B

Question

Quizplus · Accepted Answer

When a positively charged rod is brought near sphere A but doesn't touch it, electrons in the spheres (A and B, since they are touching and conductive) will be attracted towards the rod (towards sphere A). This leaves sphere A with a higher concentration of negative charge (electrons) near the rod, and sphere B with a deficiency of electrons (or a relative positive charge). When the spheres are separated while the rod is still near, sphere A retains more electrons (negative charge) near the point closest to the rod, and sphere B, having given up some electrons to sphere A, becomes positively charged due to the imbalance created.
