Q136 / 180 · AIIMS 2001 · Physics

Assertion : At pole value of acceleration due to gravity $(g)$ is greater than that of equator. Reason : Earth rotates on its axis in addition to revolving round the sun.

  • Correct answer
    A
    If both $A$ and and Reason are true and Reason is the correct explanation of Assertion.
  • B
    If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
  • C
    If Assertion is true but Reason is false.
  • D
    If Assertion is false but Reason is true.

Solution

Because of the rotation of the earth, the value of acceleration due to gravity changes. Due to this rotation, the value of ' $g$ ' becomes minimum at the equator and maximum at the poles.

Hence, the correct answer is option: 'A'.
