Question
A wedge of mass 2m a and cube of mass m are shown in figure. Between cube and wedge, there is no friction. The minimum co-efficient of friction between wedge and ground so that wedge does not move is :-
Options
A.0.10
B.0.20
C.0.25
D.0.50
Solution
Fhorozontal = Mgcubecosθsinθ
Nwedge = Mgwedge + Mgcubecos θcosθ
Nwedge = Mgwedge + Mgcubecos θcosθ
