Question
Discuss the variation of $'g\ '$
- Due to height.
- Due to depth.
✓
Answer
- $\text{g}=\text{g}\Big(1-\frac{2\text{h}}{\text{R}}\Big)$
- $\text{g}'=\text{g}\Big(1-\frac{\text{d}}{\text{R}}\Big)$
The value of $g$ decreases both on moving up and on moving down from the surface of earth. This can be shown graphically as above.
