Acceleration Due to Gravity

The average density of the earth is [g is acceleration due to gravity]

Show answer and solution

Answer: (b)

  1. g=43πGρR⇒ρ=3g4πGRg = \frac{4}{3}\pi G\rho R \Rightarrow \rho = \frac{3g}{4\pi GR}.
  2. For fixed RR and GG, ρ∝g\rho \propto g.
  3. So the answer is (b) directly proportional to gg.
