Read the assertion and reason carefully to mark the correct option out of the options given below:
Assertion: There is no effect of rotation of earth on acceleration due to gravity at poles.
Reason: Rotation of earth is about the polar axis.
  • a)
    If both assertion and reason are true and the reason is the correct explanation of the assertion.
  • b)
    If both assertion and reason are true but reason is not the correct explanation of the assertion.
  • c)
    If assertion is true but reason is false.
  • d)
    If the assertion and reason both are false.
Correct answer is option 'A'. Can you explain this answer?

As the rotation of earth takes place about polar axis therefore body placed at poles will not feel any centrifugal force and its weight or acceleration due to gravity remains unaffected.

Understanding the Assertion
The assertion states that there is no effect of Earth's rotation on acceleration due to gravity at the poles. This is true because:
- At the poles, the rotational motion of the Earth does not contribute to any centrifugal force that would affect the gravitational force.
- The gravitational pull at the poles remains essentially the same due to the Earth's mass distribution.
Analyzing the Reason
The reason given is that rotation of the Earth is about the polar axis. This statement is also true because:
- Earth rotates around an axis that runs from the North Pole to the South Pole.
- This rotation does not create any centrifugal force at the poles, which means the acceleration due to gravity is unaffected.
Conclusion
Since both the assertion and the reason are true, and the reason accurately explains why the assertion holds, the correct option is:
- a) If both assertion and reason are true and the reason is the correct explanation of the assertion.
Key Points
- Assertion: No effect of Earth's rotation on gravity at poles.
- Reason: Rotation is about the polar axis.
- Correct Option: a) Both are true, and the reason explains the assertion.
Understanding this relationship enhances comprehension of gravitational forces and the influences of Earth's rotation on them, especially at different latitudes.
