Question
Consider a special situation in which both the faces of the block 
are smooth, as shown in adjoining figure. Mark out the correct statement(s)
- If F = 0, the blocks cannot remain stationary
- for one unique value of F, the blocks M and m remains stationary with respect to block
- there exist as a range of F for which blocks M and m remain stationary with respect to block
- since there is no friction, therefore, blocks M and m cannot be in equilibrium with respect to
The correct answer is: If F = 0, the blocks cannot remain stationary
