Three identical conducting spheres are arranged on insulating stands and equally spaced, as shown. Sphere 1 initially has a net charge of Qo. while spheres 2 and 3 are initially uncharged. Sphere 1 is touched briefly to sphere 2 and moved away, then sphere 2 is touched briefly to sphere 3 and moved away An external force moves sphere 3 a distance d to the right, and sphere 3 returns to rest. During this process, the external force does an amount of work +W on sphere 3. How much total work do the electric forces from spheres 1 and 2 do on the system containing only sphere 3 during this process? -W B Zero +W D +2W
