Question

5.3 Find the acceleration due to gravity on the surface of the Mars. The mass of Mars is 6.42x1023 kg and its radius is 3370 km. (3.77 ms?​

Answer 1

Answer:

Mass of Mars = Mm = 6.42 × 1023 kg

Radius of Mars = Rm = 3370 km = 3370 × 1000 m = 3.37 × 108 m

Acceleration due to gravity of the surface of Mars = gm =?

gm = G Mm/R2m

or gm = 6.673 × 10-11 × 6.42*1023 / (3.37*106)2

= 6.673*10-11 * 6.42*1023 / 11.357

= 42.84/11.357 = 3.77 m-2

Answer 2

answer will be 3.77×10^6
