Laws of MotionHard

Question

A constant force F is applied in horizontal direction as shown. Contact force between M and m is N and between m and M′ is N′ then

Options

A.N = N′
B.N > N′
C.N′ > N
D.cannot be determined

Solution


F − N = Ma    [Newtons law for block of mass M] 
N − N′ = ma    [Newtons law for block of mass m]
N′ = M′a    [Newtons law for block of mass M′]
⇒    N′ = M′
N = (m + M′)         ⇒    N > N′
