Gravitation Question 190
Question: According to Kepler, the period of revolution of a planet (T) and its mean distance from the sun (r) are related by the equation [EAMCET (Med.) 1995; MH CET 2000; Pb. PET 2001]
Options:
A) $ [T^{3}r^{3}=] $ constant
B) $ [T^{2}{{r}^{-3}}=] $ constant
C) $ [Tr^{3}=] $ constant
D) $ [T^{2}r=] $ constant
Show Answer
Answer:
Correct Answer: B
Solution:
$ [\frac{T^{2}}{r^{3}}=] $ constant $ [\Rightarrow ,T^{2}{{r}^{-3}}] $ = constant
