Three boxes rest side-by-side on a smooth, horizontal floor. their masses are 5.0 kg, 3.0 kg, and 2.0 kg, with the 3.0-kg mass in the center. a force of 50 n pushes on the 5.0-kg box, which pushes against the other two boxes. what magnitude force does the 5.0-kg box exert on the 3.0-kg box?

25 N

Explanation:

Given

mass of 5 , 3 & 2 kg blocks lie on floor

Force on 50 N pushes the 5 kg box

be the reaction on 2 kg box therefore

where a is the acceleration of the system

reaction on 3 kg block by 5 kg block

Now for 5 kg block

F=10a

Force exerted by 5 kg block on 3 kg block is

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
