Gravitation Question 114
Question: An artificial satellite moving in a circular orbit around the earth has a total (kinetic + potential) energy $ [E_{0}] $ . Its potential energy is [IIT 1997 Cancelled; MH CET 2002; MP PMT 2000]
Options:
A)$ [-E_{0}] $
B) $ [1.5,E_{0}] $
C) $ [2,E_{0}] $
D) $ [E_{0}] $
Show Answer
Answer:
Correct Answer: C
Solution:
Potential energy = 2 × (Total energy) = $ [2E_{0}] $ Because we know = $ [U=\frac{-GMm}{r}] $ and $ [E_{0}=\frac{-GMm}{2r}] $
