# 6,7 & 86) Three blocks A,B and C are suspended as shown in figure.  Mass of each block A and C is m, if system is in equilibrium and mass of B is M thena)M=2m b) M<2m c) M>2m d) M=m7) In the arrangement shown in figure pullys are massless and frictionless and threads are light and inextensible. Block of mass m1 will remain at rest ifa) 1/m1=1/m2 + 1/m3 b) 4/m1= 1/m2 + 1/m3 c) m1=m2+m3 d) 1/m3= 2/m2 + 3/m18) A uniform rope of length L and mass M is placed on a smooth fixed wedge as shown. Both end of rope are at same horizontal level. The rope is initially released from rest, then the magnitude of initial acceleration is
