An artificial satellite moving in a circular orbit at a distance \(h\) from the centre of the Earth has a total energy \(E_0\). Then, its potential energy is
- A \(-E_0\)
- B \(1.5 E_0\)
- C \(E_0\)
- D \(2 E_0\)
Answer & Solution
Correct Answer
(D) \(2 E_0\)
Step-by-step Solution
Detailed explanation
Potential energy, \(U=\frac{-G M m}{h}\) Total energy, \(E_0=\frac{-G M m}{2 h}\) Hence, potential energy \(=2 \times\) Total energy \[ \begin{aligned} & =2 \times E_0 \quad\left(\because \text { Total energy }=E_0\right) \\ & =2 E_0 \end{aligned} \]
