When identical point charges are placed at the vertices of a cube of edge length `\'a\'` each of them experiences a net force of magnitude `F`. Now these charges are placed on the vertices of another cube of edge length `\'b\'`. What will be magnitude of the net force on any of the charges? These cubes are simply geometrical constructs and not made by any matter.
