SphereYis then brought close toXon theside opposite to the rubber rod.Yis allowedto touchXand then is removed some distanceaway. The rubber rod is then moved far awayfromXandY.What are the final charges on the spheres? Explanation: When the negatively charged rod moves close to the sphere X , the negatively charged electrons will be pushed to sphere Y . If X and Y are separated before the rod moves away, those charges will remain on X and Y , so X is positively charged and Y is negatively charged. 002 10.0points
