125. A large conducting sphere labeled X contains an electrical charge

Q

. 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

\left(\mathrm{E}_{\mathrm{y}}\right)

at the surface of sphere

Y

compare to the electrical field

\left(E_{x}\right)

at the surface of sphere

X

? (A)

\mathrm{E}_{\mathrm{x}}=\mathrm{E}_{\mathrm{y}}=0

(B)

\mathrm{E}_{\mathrm{y}}=\mathrm{E}_{\mathrm{x}} \neq 0

(C)

\mathrm{E}_{\mathrm{y}}<\mathrm{E}_{\mathrm{x}}

(D)

\mathrm{E}_{\mathrm{y}}>\mathrm{E}_{\mathrm{x}}
