Gravitation Question 295
Question: a planet in elliptical orbit around the sun 5’. Where is the kinetic energy of the planet maximum?
Options:
A) $ [P_{1}] $
B) $ [P_{2}] $
C) $ [P_{3}] $
D) $ [P_{4}] $
Show Answer
Answer:
Correct Answer: D
Solution:
-
Angular momentum of the planet about S is conserved.
So, $[mvr=]$ constant. $ [v] $ is maximum when r is minimum.
So, v is maximum at point$ [P_{4}] $ . Hence K.E. is maximum at$ [P_{4}] $ .
