An electric field around two charged objects is shown. Two spheres next to each other. Vectors perpendicular to each surface spread out and go to the other charge. The vectors are from the charge on the left, labeled X, and to the other charge, labeled Y. The vectors on the opposite sides of the charges are not bent. What are the charges of objects X and Y? X: negative Y: positive X: positive Y: positive X: negative Y: negative X: positive Y: negative
