Irene says that Earth’s force of gravity is stronger on a piece of iron than on a piece of wood of the same mass. Do you agree? Defend your answer.
Whether one can agree that Earth’s force of gravity is stronger on a piece of iron than on a piece of wood of the same mass.
Explanation of Solution
Introduction:
The force of gravity is the attractive force between any two bodies that are having mass. This force is always attractive because it continuously attempts to pull the bodies together and never tries to push them away from each other. The force of gravity is one of the fundamental forces in nature which is responsible for the interactions among the objects in nature. This is the weakest among the four fundamental forces in nature − Strong nuclear force, Electromagnetic force, weak nuclear force, and gravitational force.
Law of universal gravitation states that gravitational force
Where
It is given that mass of the iron piece and wooden piece are equal, then from the equation
