b) Both A and R is true, but R is not the correct explanation of the

assertion.

c) A is true, but R is false.

d) A is false, but R is true
Assertion (A) : The value of acceleration due to gravity of earth

does not depend upon mass of the body.
Reason (R): Acceleration due to gravity is a constant quantity.​

Answer 1

Answer:

A)

Explanation:

HERE IS YOUR ANS.

BECAUSE A AND R ARE TRUE AND R IS CORRECT

Answer 2

(c) A is true, but R is false is the correct option

Explanation:

• It's important to remember that g is a constant because it's calculated using just constants. where Re is the earth's radius. Because the earth is not a perfect spherical, the value of gravity, g, is not constant at all points on its surface.
• Regardless of direction, any item influenced exclusively by gravity (a projectile or an object in free fall) has an acceleration of 9.81m/s2. When climbing up, the acceleration is negative since the speed is decreasing.
• As a result, we treat gravity's acceleration as a constant for practical reasons.We should be aware that gravity's acceleration is always negative.
