A synchronous orbit of the Earth has a radius RRR. A planet has a mass three times the mass of the Earth. A day on the planet is half of an Earth day.
What is the radius of a synchronous orbit for this planet?
332R\frac{\sqrt[3]{3}}{2} R233R
632R\frac{\sqrt[3]{6}}{2} R236R
323R\sqrt[3]{\frac{3}{2}} R323R
34R\frac{3}{4} R43R
