SATHEE: Gravitation Question 156

Gravitation Question 156

Question: Escape velocity on earth is 11.2 km/s. What would be the escape velocity on a planet whose mass is 1000 times and radius is 10 times that of earth[DCE 2001; DPMT 2004]

Options:

A) 112 km/s

B) 11.2 km/s

C) 1.12 km/s

D) 3.7 km/s

Show Answer

Answer:

Correct Answer: A

Solution:

$[\frac{v_{p}}{v_{e}} = \sqrt{\frac{M_{p}}{M_{e}} \frac{R_{e}}{R_{p}}} = \sqrt{(1000) \times (\frac{1}{10})} = 10]$ $[v_{p} = 10 \times 11.2 = 112 k m / s]$
