Question: 5. Planets have been observed orbiting a star in another solar system. Measurements are made of the orbital radius r and the time period

5. Planets have been observed orbiting a star in another solar system.

5. Planets have been observed orbiting a star in another solar system. Measurements are made of the orbital radius r and the time period T of each of these planets. The variation with R cubed of T squared is shown in the graph below. 2.6- 2.4- 2.2- T/year 2.0- 1.8 1.6- 1.4 1.2 1.0- 0.8- 0.6- 0.4- 0.2- 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1.0 1.1 1.2 R/1034 m A) Using the graph, determine the mass of the star that the planets orbit.
