Question

Assertion: The acceleration experienced by an object during free fall is dependent on its

mass.

Reason: All objects hollow or solid, big or small, should fall at the same rate.

(I) Both A and R are true and R is the correct explanation of assertion.

(II) Both A and R are true but R is not the correct explanation of assertion.

(III) A is true but R is false.

(IV) A is false but R is true.​

Answer 1

Answer:

Both A and R are true and R 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.

Answer 2

Answer:

Both A and R are correct, and R is the correct explanation of accretion....
