(a) what is the acceleration due to gravity on the surface of the moon?
(b) on the surface of mars?
the mass of mars is 6.418×1023kg and its radius is 3.38×106m .

Explanation:

a) Acceleration due to gravity

         G = 6.67 × 10⁻¹¹ m² kg⁻¹ s⁻²

  Mass of moon, M = 7.35 × 10²² kg

  Radius of moon, r = 1.73 × 10⁶ m

  Substituting

Acceleration due to gravity on the surface of the Moon is 1.64 m/s²

b) Acceleration due to gravity

         G = 6.67 × 10⁻¹¹ m² kg⁻¹ s⁻²

  Mass of Mars, M = 6.418 × 10²³ kg

  Radius of Mars, r = 3.38 × 10⁶ m

  Substituting

Acceleration due to gravity on the surface of the Mars is 3.75 m/s²
