A hanging block of mass m' prevents the smaller block of mass m from slipping over a movable triangular block of mass M. All the surfaces are frictionless and the strings and the pulleys are light. Value of mass m' in terms of m, M and 
is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
Pulling force is m'g, while mass in motion is m + M + m'. So, acceleration of the system will be given by
.... (i)
Mass m will not slide over M if
.... (ii)
From equation (i) in (ii), we get
or
