125. A large conducting sphere labeled X contains an electrical charge QQ. Sphere X is connected by a metal wire to a small uncharged conducting sphere labeled Y . The wire is then removed. How does the electrical field (Ey)\left(\mathrm{E}_{\mathrm{y}}\right) at the surface of sphere YY compare to the electrical field (Ex)\left(E_{x}\right) at the surface of sphere XX ? (A) Ex=Ey=0\mathrm{E}_{\mathrm{x}}=\mathrm{E}_{\mathrm{y}}=0 (B) Ey=Ex≠0\mathrm{E}_{\mathrm{y}}=\mathrm{E}_{\mathrm{x}} \neq 0 (C) Ey<Ex\mathrm{E}_{\mathrm{y}}<\mathrm{E}_{\mathrm{x}} (D) Ey>Ex\mathrm{E}_{\mathrm{y}}>\mathrm{E}_{\mathrm{x}} (A) Ex=Ey=0\mathrm{E}_{\mathrm{x}}=\mathrm{E}_{\mathrm{y}}=0 (B) Ey=Ex≠0\mathrm{E}_{\mathrm{y}}=\mathrm{E}_{\mathrm{x}} \neq 0 (C) Ey<Ex\mathrm{E}_{\mathrm{y}}<\mathrm{E}_{\mathrm{x}} (D) Ey>Ex\mathrm{E}_{\mathrm{y}}>\mathrm{E}_{\mathrm{x}}
