Assertion There is no effect of rotation of earth on acceleration due to gravity at poles.
Reason Rotation of earth is about 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 the Reason is nor the correct explanation of the Assertion
• C. if Assertion is true but Reason is false
• D. if Assertion and Reason are false
