As you move to a higher altitude above the Earth's surface or deep below it, the value of g
AIncreases in both cases
BDecreases in both cases
CIncreases with height but decreases with depth
DStays constant in both cases
Answer & Solution
Correct answer: B. Decreases in both cases
1. Moving up from the surface increases the distance from the centre, so g reduces.
2. Moving deep below the surface also reduces g, becoming zero at the centre.
3. So g decreases both with increasing height and with increasing depth.
