Two blocks of masses M = 3 kg and m = 2 kg, are in contact on a horizontal table. A constant horizontal force F = 5 N is applied to block M as shown. There is a constant frictional force of 2 N between the table and the block m but no frictional force between the table and the first block M, then the acceleration of the two blocks is-
(A) 0.4 ms–2
(B) 0.6 ms–2
(C) 0.8 ms–2
(D) 1 ms–2
