The identical conducting spheres, I, II, III, are mounted on insulating stands and place as shown. Spheres I and II are each uncharged, and III carries a net positive charge. Spheres I and II are connected to each other by a conducting wire. After the wire is removed, sphere III is moved far away. Which of the following statements about the subsequent charges on spheres I and II is correct?
A) Sphere I is negatively charged and sphere II is positively charged
B) Sphere I is positively charged and sphere II is negatively charged
C) they are charged with equal negative charges
D) they are each still uncharged

Answer #1

When two charged shpere connect by a wire and after some time wire is removed, after removing of wire charge on each sphere is average of previous sphere.

But in given question spheres uncharged, so after the removing of wire they are still uncharged.

Option D is correct.

They are still uncharged.

    ere are two identical, positively charged conducting spheres fixed in space. The spheres are 43.4 cm apart (center to center) and repel each other with an electrostatic force of F10.0795 N. Then, a thin conducting wire connects the spheres, redistributing the charge on each sphere. When the wire is removed the spheres still repel but with a force of F2 0.115 N.
