Gravitation Question 209
Question: If orbital velocity of planet is given by $ [v=G^{a}M^{b}R^{c}] $ , then[EAMCET 1994]
Options:
A) $ [a=1/3,,b=1/3,,c=-1/3] $
B) $ [a=1/2,,b=1/2,,c=-1/2] $
C) $ [a=1/2,,b=-1/2,,c=1/2] $
D) $ [a=1/2,,b=-1/2,,c=-1/2] $
Show Answer
Answer:
Correct Answer: B
Solution:
$ [v=\sqrt{\frac{GM}{R}}] $
$ [={{G}^{1/2}}{{M}^{1/2}}{{R}^{-1/2}}] $
