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
Answers
Answer:
B)
Explanation:
Both assertion and reason are true but reason is not the correct explanation of assertion
As both the statements are correct but "The force of gravitation exerted by the earth is called gravity." which is the reason doesn't explain the assertion i.e."Any two objects in the universe attract each other by a force called gravitation force."
Answer:
(a) Both assertion and reason are true and reason is the correct explanation of assertion.
Explanation:
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/s ^2
depending on lattitude, with a conventional standard value of exactly 9.80665m/s ^2.
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.
Hence, Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
