Question

A block of mass M is kept on the floor . Consider weight W as action . what is its reaction?
a) Normal by block on floor
b) Normal by floor on block
c) Gravitational force by block on earth
d) Gravitational force by earth on block​

Answer 1

When a block of mass M is kept on the floor with weight W acting as action, a reaction in the form of (b) normal by floor on block will be created.

Here, according to the given information, we are given that,

A block of mass M is kept on the floor. Let weight W be considered here as action.

Now, if we start representing the block of mass M on a horizontal surface, then here we will see that the weight Mg of the given block will act downwards. Here g is the gravitational force of acceleration.

Also, the normal will be acting on the block but in an upward direction.

Here, due to the action of the weight W, there will be a reaction in the form of the normal that has been created by the floor on the block.

Hence, when a block of mass M is kept on the floor with weight W acting as action, a reaction in the form of normal by floor on block will be created.

Answer 2

Answer:

If a block of mass M having weight W is kept on the floor a normal force will be acting by the block on the floor and a gravitational force by the earth on the block.

Explanation:

• Two forces act on the block, its weight and the normal force exerted by the surface of the table.
• Newton's third law states that for every action (force) in nature, there is an equal and opposite reaction. This plays an important role in connection with the normal force.
