Acceleration Due to Gravity question from JEE Main 2005 (AIEEE)

Q126JEE Main 2005 · AIEEEEasy

Acceleration Due to Gravity

Average density of the earth

Show answer and solution

Answer: (d)

$g = \frac{4}{3}\pi G\rho R \Rightarrow \rho = \frac{3g}{4\pi GR}$ .
With $G$ and $R$ fixed, $\rho \propto g$ .
So the answer is (d) directly proportional to $g$ .
