Consider a special situtation in which both the faces of the block M0 are smooth, as shown in adjoining figure. Mark out the correct statement(s)
(A) If F=0, the blocks M and m cannot remain stationary
(B) For one unique value of F, the blocks M and m remain stationary with respect to block M0
(C) There exists a range of F for which blocks M and m remain stationary with respect to block M0
(D) Since there is no friction, therefore, blocks M and m cannot be in equillibrium with respect to block M0
