Three identical conducting spheres are fixed along a single line. the middle sphere is equidistant from the other two so that the center-to-center distance between the middle sphere and either of the other two is 0.345 m. initially, only the middle sphere is charged, with qmiddle+27.6 nc. the middle sphere is later connected by a conducting wire to the sphere on the left. the wire is removed and then used to connect the middle sphere to the sphere on the right. the wire is again removed (a) what is the charge on each sphere? left sphere middle sphere right sphere rnc. nc nc (b) which sphere experiences the greatest electrostatic force? o left sphere o middle sphere o right sphere (c) what is the magnitude of that force?
