Question

Two identical smooth disc of radius R have been
placed on a frictionless table touching each other.
Another circular plate is placed between them as
shown in figure. The mass per unit area of each
object is o, and the line joining the centers of the
plate and the disc is e
(a) Find the minimum horizontal force F. that
must be applied to the two discs to keep them
together.
(b) Angle can be changed by changing the size
of the circular plate. Find F, when 0+ 0.
