ii) A teacher while discussing gravitation introduced a quantity that depends only on mass and
radius of the earth and is same for all objects at a given point on the earth. Which quantity the
teacher is referring to?
iii) Virat studied variation in acceleration due to gravity (g) with certain quantity. He observed g
decreases as this quantity is increased and becomes zero as that quantity becomes infinite. Which
quantity is studied by Virat?
Answers
Answer:
The gravitational field strength on the Earth's surface is approximately 9.81 m/s². Virat is likely studying the relationship between the acceleration due to gravity and the altitude or height from the surface of the Earth.
Explanation:
The teacher is most likely referring to the gravitational field strength, also known as acceleration due to gravity (g), which is a measure of the gravitational force experienced by an object per unit mass at a given point in space.
The value of g depends on the mass and radius of the celestial body, in this case, the Earth, and is the same for all objects at a given point on the Earth's surface. The gravitational field strength on the Earth's surface is approximately 9.81 m/s².
On the other hand, Virat is likely studying the relationship between the acceleration due to gravity and the altitude or height from the surface of the Earth. The acceleration due to gravity decreases with increasing altitude because the distance between the object and the center of the Earth increases, and thus the gravitational force decreases.
At an infinite distance from the Earth's surface, the acceleration due to gravity becomes zero, as there is no gravitational force acting on the object. This quantity is known as the gravitational potential energy per unit mass or the gravitational potential, and it is a scalar quantity that represents the work required to move an object from infinity to a given point in space.
