A cube of mass m is placed on top of a wedge of mass 2 m as shown in Fig. between the cube and the wedge. The minimum co- efficient of friction between the wedge and the hori- zontal surface so that the wedge does not move is There is no friction (a) 0.1 (b) 0.2 (c) 0.3 (d) Cube m Wedge 2 m 045 45 Slide 28 of 70
