This problem is SOLVED.

I made it a much smoother number. Thanks for the help Doc. This Problem is SOLVED.

Oh. Thanks for the response. So for sun and Earth use: 1.5*10^11^2 ... or 149,668,992,000^2 and for moon and Earth use: 384,000,000^2 ...? thanks again doc.

So for sun and earth... 6.67*10^-11(5.97*10^24)(1.99*10^30)/ r2 I'm not sure what the radius would be. I thought it would be the distance between the sun and the earth. Which radius would I use, that of the Earth or that of the sun? For the moon and...

Posted 2 problems up so far in the Homework, General Physics section. I can't post links because my post count is< 15. :cry:

Homework Statement "Calculate the gravitational force between: A) The sun and the earth B)The moon and the earth" Homework Equations F= M/r2 The Attempt at a Solution A)The sun and the earth Earth: mass 5.97*10^24 kg Radius 6,380,000 meters Sun: mass 1.99*10^30 Radius...

Thanks for the welcome! Thanks for the feedback also. No, I didn't mean to put that "g" at the end.:cool:

Homework Statement "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. Homework Equations Gmp/rp2 Mp is mass of planet Rp is radius of planet The Attempt at a Solution First off I needed to change the...

hah thought I'd try. I'll post the answers up in a few hours.:approve:

Just interested in seeing what peoples answers are to these questions. I am new to the site so this could be considered a test of how well the members of this forums acutally know physics.{I've done this problems and have answers} Interested in seeing which equations you used also. Problem...
