Three blocks of mass 1 kg, 4 kg and 2 kg are placed on a smooth horizontal plane as shown in the figure. The contact force between 1 kg block and 4 kg block is

Options:

Answer:

Solution:

Treat all three blocks as one system (total mass 7 kg). Net force $= 120 - 50 = 70 N$ .

$70 = 7 a \Rightarrow a = 10 m/ s^{2}$ .

For the 1 kg block: $120 - F = 1 \times 10 \Rightarrow F = 110 N$ .
