Highly selective Backlog Qs for JEE MainPhysicsLaws of Motion

Three blocks are pushed with a force F across a frictionless table as shown in figure. Let N ₁ be the contact force between the left two blocks and N ₂ be the contact force between the right two blocks. Then

Options

  1. AF>N₁>N₂
  2. BF>N₂>N₁
  3. CF>N₁=N₂
  4. DF=N₁=N₂

Correct answer

A. F>N₁>N₂

Step-by-step solution

F =6 a , N ₁=5 a , N ₂=3 a F > N ₁> N ₂
