Assume body B to be uniform:
|Column-A||Column-B (Torque of|
normal reaction on body B
about centre of mass)
(F is directed towards|
|(s)||Conclusion cannot be drawn|
with the information given
To balance torque due to f, N will shift downwards
(For rotational equilibrium (about C)
Normal will shift towards left.
(For rotational equilibrium
Frictionless surface. So, no torque about C.M. So
normal will not shift and will pass through C.M.
