With the following assumptions:
1. The lamina are disks
2. "Vanishingly thin" => thickness of disk << radius of disk
3. "two spheres [separated] by a similar distance"
=> the two spheres are essentially in contact.
The force is weaker, LOTS weaker, by as large a factor as you'd
like because it is directly proportional to the thickness of the
disk.
