There is a planet which is 8 times massive and 27 times denser than the earth. If \(g^{\prime}\) and \(g\) are the accelerations due to gravity on the surfaces of the planet and the earth respectively then
- A \(g^{\prime}=8 \mathrm{~g}\)
- B \(g^{\prime}=27 \mathrm{~g}\)
- C \(g^{\prime}=18 \mathrm{~g}\)
- D \(g^{\prime}=\frac{9}{4} g\)
Answer & Solution
Correct Answer
(C) \(g^{\prime}=18 \mathrm{~g}\)
Step-by-step Solution
Detailed explanation
Let, \(d=\) Density of planet, \(\begin{aligned} & M=\text { Mass of planet } \\ & R=\text { Radius of planet }\end{aligned}\) then density, \(d=\frac{\text { Mass }}{\text { Volume }}\)…
