# Two satellites, X and Y, move in circular orbits around the same planet. Satellite X has mass \(m\) and orbits at a distance \(R\) from the planet’s center. Satellite Y has mass \(2m\) and orbits at a distance \(4R\) from the planet’s center. If the orbital speed of Satellite X is \(v_0\), what is the orbital speed of Satellite Y?

Two satellites, X and Y, move in circular orbits around the same planet. Satellite X has mass \(m\) and orbits at a distance \(R\) from the planet's center. Satellite Y has mass \(2m\) and orbits at a distance \(4R\) from the planet's center. If the orbital speed of Satellite X is \(v_0\), what is the orbital speed of Satellite Y?

- **A.** \(\dfrac{1}{4} v_0\)
- **B.** \(\dfrac{1}{2} v_0\)
- **C.** \(v_0\)
- **D.** \(2 v_0\)
