A block of mass mlies on wedge of mass M as shown in figure. Answer following parts separately. (a)Withwhat minium acceleration must the wedge be moved towards right horizontally so that block m falls freely.

( b)Find the minimum friction coefficient required between wedge M and ground so that it does not move while block m slips down on it.
