Homework Statement
Two neutral metal spheres of radius r and mass m each are connected by a light flexible conducting string of length L. The spheres are placed in a uniform electrostatic field E directed along the line connecting the centers of the spheres. Initially, the spheres are at rest a distance l from each other (r << l < L). Find the maximum speed v of the spheres after they are released. Neglect gravitational effects.
The Attempt at a Solution
I don't see any reason why would the spheres start moving towards each other when they are released. The question itself states that the spheres are neutral. They will not experience any electrostatic force.
