When man stands on a bathroom scale here on Earth, it reads 560N . Assume each planet to be a perfect sphere with the following parameters. What would his mass be on Mars if Mars has a mass of 6.419 x 10^23 kg and a radius of 3.396 x10^6 m?

Question

and what is the magnitude of the gravitational force Mars would exert on man if he stood on its surface?

Answer 1

The mans mass would be the same as on earth so its just 560/9.8=57.14kg

Second part is F=[(Gconstant)(m one)(m two)]/(radius)^2

G constant is 6.67E-11
