Gravitation Question 266
Question: A satellite with kinetic energy $ [E_{k}] $ is revolving round the earth in a circular orbit. How much more kinetic energy should be given to it so that it may just escape into outer space [KCET (Engg./Med.) 2001]
Options:
A) $ [E_{k}] $
B) 2$ [E_{k}] $
C) $ [\frac{1}{2}E_{k}] $
D) 3$ [E_{k}] $
Show Answer
Answer:
Correct Answer: A
Solution:
Binding energy = ? kinetic energy And if this amount of energy $ [(E_{k})] $ given to satellite then it will escape into outer space
