Answer:
Sphere X is positively charged while sphere Y is negatively charged
Explanation:
The method described in the given experiment is known as charging by induction. Charging by induction is a method used to charge an object without actually touching the object to any other charged object
When a negatively charged rubber rod is brought near the uncharged sphere X, charges are induced in the metal sphere. Positive charges are attracted to to the rubber rod whereas negative charges are repelled away from the rod. Since the spheres are mounted on insulated stands, the induced charges remain on the sphere. When sphere Y is made to touch sphere X, the negative charges from X flow into Y leaving it with excess negative charges. When Y is then removed from X, the excess negative charges are then evenly distributed across the surface of Y. Finally, the rubber rod is moved far way from X leaving X with excess positive charges due to the electrons that have flowed from it into Y.
