A wedge `B` of mass 2 m is placed on a rough horizontal suface. The coefficient of friction between wedge and the horizontal surface is `mu_(1)`. A block of mass m is placed on wedge as shown in the figure. The coefficient of friction between block and wedge is `mu_(2)`. The block and wedge are released from rest.
Q. Suppose the inclined surface of the wedge is at `theta=37^(@)` angle from horizontal and `mu_(2)=0.9` then the wedge:
A. will remain in equilibrium if `mu_(1)=0.5`
B. will accelerate towards left if `mu_(1)=0`
C. will acceleration toward left if `mu_(1)=0.25`
D. will remain in equilibrium if `mu_(1)=0.3`
