Assertion Reason Questions on Gravitation
Assertion Reason Questions
Directions:
Each of the following questions consists of two statements: an Assertion (A) and a Reason (R). Answer them by selecting the correct option:
(a) Both Assertion (A) and Reason (R) are true, and Reason (R) is the correct explanation of Assertion (A).
(b) Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of Assertion (A).
(c) Assertion (A) is true, but Reason (R) is false.
(d) Assertion (A) is false, but Reason (R) is true.
Q1. Assertion (A): The gravitational force is the weakest fundamental force in nature.
Reason (R): Gravitational force acts only on massive bodies.
Answer: (c) Assertion is true, but Reason is false.
Difficulty Level: Moderate
Q2. Assertion (A): The acceleration due to gravity decreases with increase in altitude.
Reason (R): $g \propto \frac{1}{(R+h)^2}$, where $R$ is the Earth’s radius and $h$ is the altitude.
Answer: (a) Both $A$ and $R$ are true, and $R$ is the correct explanation of $A$.
Difficulty Level: Moderate
Q3. Assertion (A): The value of $g$ is same at all points on Earth’s surface.
Reason (R): Earth is a perfect sphere.
Answer: (d) Assertion is false, but Reason is true.
Difficulty Level: Tough
Q4. Assertion (A): Gravitational potential is always negative.
Reason (R): Work is done against gravitational force to bring a mass from infinity to a point.
Answer: (a) Both A and R are true, and R is the correct explanation of A.
Difficulty Level: Tough
Q5. Assertion (A): Satellites are accelerated even though they move in uniform circular motion around the Earth.
Reason (R): The gravitational force provides the necessary centripetal force.
Answer: (b) Both A and R are true, but R is not the correct explanation of A.
Difficulty Level: Moderate
