Acceleration Due to Gravity and its variation

Question 51: easy

Which of the following statements are true about acceleration due to gravity (g)? (where symbols have their usual meaning)?

1. g will not change at poles if earth stops rotating on its axis

2. The value of acceleration due to gravity decreases as we move away from surface of earth

3. The value of acceleration due to gravity decreases as we move from surface towards centre of earth

4. All of these

View Answer

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