Homework Statement




Initially, metal sphere X is charged to an electric potential of 10,000 volts, with a total charge on its surface of +Q. Metal spheres Y and Z are initially uncharged. Spheres Y and Z are the same size as sphere X. All three spheres are held by insulated stands.


6. Sphere X is connected by a conducting wire to sphere Y. The wire is then removed and used to connect sphere Y and Z. After the wire is again removed, what is the potential on sphere Z?
a. 10,000 V
b. 5,000 V
c. 2,500 V
d. 1,250 V
e. 0
7. What is the charge on sphere Z after the procedure described in problem 6?
a. +Q
b. + ½ Q
c. + ¼ Q
d. + 1/3 Q
e. –Q
