SATHEE: Gravitation Question 162

Gravitation Question 162

Question: The escape velocity of a body on an imaginary planet which is thrice the radius of the earth and double the mass of the earth is $[(v_{e}]$ is the escape velocity of earth) [Kerala (Med.) 2002]

Options:

A) $[\sqrt{2 / 3}, v_{e}]$

B) $[\sqrt{3 / 2}, v_{e}]$

C) $[\sqrt{2} / 3, v_{e}]$

D) $[2 / \sqrt{3}, v_{e}]$

Show Answer

Answer:

Correct Answer: A

Solution:

$[\frac{v_{p}}{v_{e}} = \sqrt{\frac{M_{p}}{M_{e}} \times \frac{R_{e}}{R_{p}}} = \sqrt{2 \times \frac{1}{3}} = \sqrt{\frac{2}{3}}]$ \ $[v_{p} = \sqrt{\frac{2}{3}} v_{e}]$
