Solve the all parts of given problem:
Problem: The orbital speed of a planet about its star is 3.1× 104 m/s and its distance from the star is 1.6× 1011 m. The mass of the planet is approximately 6.0× 1024 kg.
Part A: What is the magnitude of the force exerted by the star on the planet?
Part B: What is the mass of the star?
I need help to determine the magnitude of the force exerted by the star on the planet.
