TWO BLOCK SYSTEM : (frictionless surface)
minimum value of F so that "m" falls freely is given by
F=Mg cot theta
wedge M moves with acceleration

explain and derive those formulae given below ? plz write all derivation steps and also show all the forces acting on the block and body .

F = m.a
F = ma cos theta
Mg cot theta = m (g cot theta) cos theta
So, M = m cos (theta)
In the case where M = m , cos theta = 1
So, theta = 0 degree.
