1. The problem statement, all variables and given/known data Consider the Sun and the Earth as a 'system' of two 'particles'. The center of mass of this system lies a distance L from the center of the Sun. Find L and compare it to the radius of the Sun. The center of mass of the Earth-Sun system lies? A. inside the radius of the Sun B. inside the radius of the Sun C. inside the radius of the Earth 2. Relevant equations 3. The attempt at a solution I have no clue where to start, I know the center of mass equation but I don't know if that has any significance or what. Thank you in advance!
