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.
