Question
There block A, B and C of equal m are placed one over the other on a smooth horizontal ground shown in figure. Coefficient of friction between any two block of A, B and C is 
. The maximum value of mass of block D so that the block A, B and C move without slipping over each other is
. The maximum value of mass of block D so that the block A, B and C move without slipping over each other isOptions
A.6 m
B.5 m
C.3 m
D.4 m
Solution
Block A and C both move due to friction. Hence less friction is available to A as com pared to C. Maximum acceleration of A = μg =
But acceleration of system a =
⇒
= 
⇒ mD = 3m
But acceleration of system a =
⇒
= ⇒ mD = 3mCreate a free account to view solution
