Assertion :
If earth suddenly stops rotating about its axis, then the value of acceleration due to gravity will become same at all the places on the surface of the earth.
[Assume earth as a perfect sphere]
Reason: The value of acceleration due to gravity is independent of rotation of the earth

Solution

The correct option is C Assertion is correct but Reason is incorrect
The value of acceleration due to gravity is maximum at poles and minimum at the equator because the centrifugal force for the earth's spinning is vanishes at poles and maximum at the equator.
If the earth suddenly stops rotating about its axis, there is no effect of centrifugal force on the gravitational acceleration. So, the value of gravitational will be same at all places.
