Of the statements, given below, mark the correct answer as:Assertion : Any two objects in the universe attract each other by a force called gravitation force.Reason : The force of gravitation exerted by the earth is called gravity.a)Both assertion and reason are true and reason is the correct explanation of assertion.b)Both assertion and reason are true but reason is not the correct explanation of assertion.c)Assertion is true but reason is false.d)Both Assertion and Reason are false.Correct answer is option 'B'. Can you explain this answer?

Question

Answer

Gravitational acceleration is the acceleration of an object caused by the force of gravity from another object. In the absence of any other forces, any object will accelerate in a gravitational field at the same rate, regardless of the mass of the object. On the surface of the Earth, all objects fall with an acceleration of somewhere between 9.78 and 9.82m/s2 depending on latitude, with a conventional standard value of exactly 9.80665m/s2.
In a place on the earth, the acceleration due to gravity is constant because it is determined by the mass, and radius of the Earth and not the properties of the object.

Answer

Assertion: Any two objects in the universe attract each other by a force called gravitation force.
Reason: The force of gravitation exerted by the earth is called gravity.

Explanation:
- Gravitation is a fundamental force that exists between any two objects with mass. It is the force of attraction that exists between all objects in the universe.
- The assertion is true because according to Newton's law of universal gravitation, every object in the universe attracts every other object with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
- The reason is also true because gravity is the specific name given to the force of gravitation exerted by the Earth. Gravity is what keeps us grounded on the Earth and is responsible for the Earth's gravitational field.
- However, the reason is not the correct explanation of the assertion. While it is true that the force of gravitation exerted by the Earth is called gravity, the assertion is a general statement that applies to any two objects in the universe, not just the Earth.
- The force of gravitation exists between any two objects, whether they are on Earth or in outer space. It is a universal force that acts between all objects with mass, regardless of their location.
- Therefore, both the assertion and reason are true, but the reason does not provide a correct explanation for the assertion. The correct answer is option 'B'.
