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}] $
