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 movesclose to the sphereX, the negatively chargedelectrons will be pushed to sphereY. IfXandYare separated before the rod moves away,those charges will remain onXandY, soXis positively charged andYis negativelycharged.00210.0points
