A planet has a mass of 5.68 x 1026 kg and a radius of 6.03 x 107 m. What is the weight of a 65.0 kg person on the surface of this planet?

Weight is dependent on both the mass of the object and the gravitational pull of a planet. This is why people weigh differently on other planets, which have a different gravitational force. Using the formula W = G (m1) (m2) / r^2 where:

W = weight or force

G = Gravitational constant (not the same as g) = 6.67x10^-11 m^2/kg^2

m1 = mass of object 1 (person)

m2 = mass of object 2 (planet)

r = radius of planet

This gives a weight of 677.26 Newtons
