"Determine the acceleration due to gravity on the planet Mercury which has a mass of 3.30*10^23kg and a diameter of 4878 km.
Mp is mass of planet
Rp is radius of planet
The Attempt at a Solution
First off I needed to change the diameter into the radius. In my class I have to convert km to m.
4878 km*1000= 4,878,000 m
2,439,000 is the radius
Next, plugged in.
(6.67*10^-11)(3.30*10^23)/2,439,000^2 = 3.70 g on Mercury.
I'm pretty sure this is correct just want to make sure. Thanks for looking it over!
