Acceleration Due to Gravity

Which of the following statements are true about acceleration due to gravity (g)? (where symbols have their usual meaning)?
g will not change at poles if earth stops rotating on its axis
The value of acceleration due to gravity decreases as we move away from surface of earth
The value of acceleration due to gravity decreases as we move from surface towards centre of earth
All of these

Solution:

All statements are correct. Rotation does not affect gravity at the poles, and gravity decreases both above and below the surface of the Earth.
