The mass of Planet X is one-tenth that of the earth, and its diameter is one-half that of the earth. the acceleration due to gravity at the surface of Planet X is most nearly...

Respuesta :

Fg=(G*M1*M2)/(r^2)

(1/10)/(1/2^2)=4/10=2/5

Planet X is approx 2/5 of earth’s gravity

9.8m/s^2 * 2/5 = 3.92m/s^2
