Hi all :)
Hope the day has been good to you...i am stuck on a question for my uni assignment, and have been stuck on this one for about 3 days to no avail...i don't even know where to start. I'm not too sure whether i need a certain equation for the question or if i have to come up with one using the information in the question...
If anyone could please help me through it would be greatly appreciated as I've only got 4 days left...if not thanks for looking anyways :)
There once was a planet - quite far
In orbit around a star
The star’s mass was ms
The planet’s mass you assess
Using the orbital radii, r
You can assume the radius of the planet’s and the star’s circular orbits around the
centre of mass of the system are rp = 1.5 × 108 km and rs = 1.0 × 106 km, respectively, with
ms = 2.0 × 1030 kg.
Calculate the mass of the planet, mp, showing all your workings and giving your answer in scientific notation to the appropriate number of significant figures.
Any help would be amazing as I'm at my wits end !
Many Thanks,
Ax
