Question

A body of 1 kg applies a force of 10 newton on a body of 4 kg. What will be the reaction of 4 kg body on the body of 1 kg?​

Answer 1

Answer:

NEWTON’S THIRD LAW OF MOTION

Whenever one body exerts a force on a second body, the first body experiences a force that is equal in magnitude and opposite in direction to the force that it exerts.

Considering this law , the 1 kg body will feel 10N force acting in the upwards direction. (Assuming that 1kg Block is on top of the 4kg block , because a block cannot exert any force if it is just kept beside another block). This force is called Normal Force.

Answer 2

★ $\large\underline\mathrm\blue{Answer \: :}$

★ NEWTON'S THIRD LAW OF MOTION :-

Whenever one body exerts a force on a second body, the first body experiences a force that is equal in magnitude and opposite in direction to the force that it exerts.

Considering this law ,

Given : the 1 kg body feel 10 Newton force upwards (↑) direction.

Now, assuming that 1 kg block in on the top of 4 kg block because block will exert force on second block only when it is on the top of block and cannot exert force if it is kept beside the box.

Here, The second block should be kept on the top of first block for exerting force on first block.
