Consider the given system. It is obvious that the weight of the block will lead the system to move in the leftward direction. But the reason for that is not clear to me.
Homework Equations
Using the FBD of the block(B):
##mg-T=ma## where ##a## is assumed its downward acceleration.
##N=mA## where ##A## is the rightward acceleration as the normal force from the bigger block A is in the right ward direction. (Which is the problem)
##T+N=M\alpha## where I assume that ##\alpha## is the acceleration of block A in the leftward direction (as both T and N are in the left direction for A)
The Attempt at a Solution
So there is nothing pulling B towards left so why will go in the left direction ¿
