Question:

Block A of mass 5kg is kept on another block B of mass 10kg, which is placed on a horizontal platform P. Assume acceleration due to gravity 10m/s² and magnitude of normal reactions between the blocks A and B is N₁ and between the block B and the platform

Block A of mass 5kg is kept on another block B of mass 10kg, which is placed on a horizontal platform P. Assume acceleration due to gravity 10m/s² and magnitude of normal reactions between the blocks A and B is N₁ and between the block B and the platform is N₂. When the platform is moving downward with acceleration 10 m/s², N₁ = N₂ = zero. When the platform is moving upward with uniform velocity of 5 m/s, N₁ = 50 N & N₂ = 150 N. When the platform is moving upward with acceleration 5 m/s², N₁ = 75N & N₂ = 225N. When the platform is moving downard with uniform velocity of 5 m/s, N₁ = 50 N & N₂ = 150 N.
