A small block of mass m is kept on a bigger block of
mass M which is attached to a vertical spring of spring
constant k as shown in the figure. The system oscillates
vertically. (a) Find the resultant force on the smaller
block when it is displaced through a distance x above
its equilibrium position. (b) Find the normal force on the
smaller block at this position. When is this force smallest
in magnitude ? (c) What can be the maximum amplitude
with which the two blocks may oscillate together ?

can someone explain
at 2:14 how did sir guess that X<Xo
X might be more than Xo we dont know???

Sir force downward kyu lagega? Force toh upward lagni chahiye na! Because their net compression x not is still greater than x

Please tell me
What if the blocks are not attached
