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′ Create a free account to view solution
