X and Y are two uncharged metal spheres on insulating stands, and are in contact with each other. A positively charged rod R is brought close to X as shown in Figure (a). Sphere Y is now moved away from X, as in Figure (b). What are the final charge states of X and Y?
(a) X is positive and Y is neutral.
(b) Both X and Y are neutral.
(c) X is negative and Y is positive.
(d) Both X and Y are negative.
(e) X is neutral and Y is positive.
Two uncharged metal balls, X and Z, stand on insulating glass rods.A third ball, carrying a negative charge, is brought near the ballZ as shown in the figure. A conducting wire is then run between Xand Z and then removed.Finally the third ball is removed.conducting wire(-) (Z)------(X)I I IWhen all this is finished Which one of the following happens?1. balls X and Z are both positive, but ballZ carries more charge than ball X.2. ball X is positive and ball Z is negative.3. balls X and Z are both positive, but ball X carries more chargethan ball Z.4. ball X is positive and ball Z is neutral.5. ball X is negative and ball Z is neutral.6. balls X and Z are still uncharged.7. ball X is neutral and ball Z is positive.8. ball X is neutral and ball Z is negative.9. balls X and Z are both negative.10. ball X is negative and ball Z is positive
