Statement I: If the earth suddenly stops rotating about its axis, then the acceleration due to gravity will become the same at all the places.
Statement II: The value of acceleration due to gravity is independent of rotation of the earth.

Options

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

Answer

C

Explanation

The value of g at any place is given by the relation
`g.=g-omega^2R_ecos^2lamda`
When `lamda` is angle of latitude and `omega` is the angular velocity of earth. If earth suddenly stops rotating, then `omega=0`
`therefore` g.=g i.e., the value of g will be same at all places.
