Average density of the earth:
- AIs directly proportional to g.
- BIs inversely proportional to g.
- CIs a complex function of g.
- DDoes not depend on g.
✓
Answer
- Is directly proportional to g.
Explanation:
$\text{g}=\frac{\text{GM}}{\text{R}^2}\times\frac{4}{3}\pi\text{R}^3\ \rho=\frac{4}{3}\pi\text{GR}\rho$
$\text{or g}\propto\rho$
