Question

1) X and Y are two initially uncharged metal spheres on insulating stands, and they are in contact with each other as shown in part (a). A negatively charged rod R is brought close to X as shown in part (b) of the figure. Sphere Y is now moved away from X manually, as shown in part (c). Finally, the rod is removed as in part (d) d describe the resulting actions that the charges are taking in part (b), (5 points) When rod s brous close t0 X, bth meds behan as ore conductor R (X si e sign of the final charge states of X and Y as shown in figure (d) ? ( 2.5 points)

Explanation / Answer

both X and Y are behave as one conductor in (b)...since negative rod is brought near to them, because of attraction positive charge is accumulated on X and and because of repulsion negative charge is accumulated on Y.
