Question: The orbital angular momentum of a satellite revolving at a distance r from the centre is L. If the distance is increased to 16r, then the new angular momentum will be [MP PET 2003]
Options:
A) 16 L
B) 64 L
C) $ [\frac{L}{4}] $
D) 4 L
Show Answer
Answer:
Correct Answer: D
Solution:
$ [L=mvr=m\sqrt{\frac{GM}{r}r}=m\sqrt{GMr},,,\therefore ,,,L\propto \sqrt{r}] $
