Jupiter has a mass of 1.91 × 10²⁷ kg and its radius is 7.14 × 10⁷ m.  What is its gravity constant?  What is the acceleration due to gravity?   

Use g = -GM

                 r²

g = - 6.67 ´ 10 ^–11 N m² kg^-2 × 1.91 × 10²⁷ kg (P)

                           7.14 × 10⁷ m

g = 25.0 N/kg (P)

Acceleration due to gravity = 25 m/s² (P)
