Answer:
The amount force exerted by the table back is 5 newton
Step-by-step explanation:
We have given that the tables is push down by a force of 5 newton
We have to find the amount of force by which the table push back
From newton's third law we know that when we applied any force on ay object then that object also exerts same amount of force but in opposite direction.
So the amount force exerted by the table back is 5 newton
So answer will be 5 newton
