Gravitation Question 210
Question: Two satellite are revolving around the earth with velocities $ [v_{1}] $ and $ [v_{2}] $ and in radii $ [r_{1}] $ and $ [r_{2}(r_{1}>r_{2})] $ respectively. Then [BHU 2005]
Options:
A) $ [v_{1}=v_{2}] $
B) $ [v_{1}>v_{2}] $
C) $ [v_{1}<v_{2}] $
D) $ [\frac{v_{1}}{r_{1}}=\frac{v_{2}}{r_{2}}] $
Show Answer
Answer:
Correct Answer: C
Solution:
$ [v=\sqrt{\frac{GM}{R}}] $
if $ [r_{1}>r_{2}] $ then $ [v_{1}<v_{2}] $
