SATHEE: Gravitation Question 165

Gravitation Question 165

Question: The escape velocity for the earth is $[v_{e}]$ . The escape velocity for a planet whose radius is four times and density is nine times that of the earth, is[MP PET 2003]

Options:

A) $[36, v_{e}]$

B) $[12, v_{e}]$

C) $[6, v_{e}]$

D) $[20, v_{e}]$

Show Answer

Answer:

Correct Answer: B

Solution:

$[v \propto R \sqrt{ρ}]$ \ $[\frac{v_{p}}{v_{e}}$ = $\frac{R_{p}}{R_{e}} \times \sqrt{{\frac{ρ_{p}}{ρ}}_{e}}$ = $4 \times \sqrt{9} = 12]$ Þ $[v_{p} = 12 v_{e}]$
