I can't seem to obtain the right answer using the escape velocity formula. I think my problem is with the gravitational constant. I would like to find the escape velocity of the sun.(adsbygoogle = window.adsbygoogle || []).push({});

[tex]v_e=\sqrt{\frac{2GM}{r}}[/tex] or [tex]v_e=\sqrt{\frac{2\mu}{r}}[/tex]

[tex]v_e_\odot=617.54(km/s)[/tex]

[tex]v_e_\odot=\sqrt{\frac{2*6.673e-11*1.9891e30(kg)}{696000(km)}}[/tex]

[tex]v_e_\odot=\sqrt{~3.8141e14}\neq 617.54(km/s)[/tex]

What am I doing wrong?

Thanks
