SATHEE: Gravitation Question 146

Gravitation Question 146

Question: The escape velocity from the surface of earth is $[V_{e}]$ . The escape velocity from the surface of a planet whose mass and radius are 3 times those of the earth will be [MP PMT/PET 1998; JIPMER 2001, 02; Pb. PMT 2004]

Options:

A) $[V_{e}]$

B) $[3 V_{e}]$

C) $[9 V_{e}]$

D) $[27 V_{e}]$

Show Answer

Answer:

Correct Answer: A

Solution:

$[v_{e} = \sqrt{\frac{2 G M}{R}}]$ \ $[v_{e} \propto \sqrt{\frac{M}{R}}]$ If mass and radius of the planet are three times than that of earth then escape velocity will be same.
