Question

find the acceleration due to gravity on the surface of the mars the mass of mars is 6.42x10ki power 23 kg and its radius is 3370km​

Answer 1

Acceleration due to gravity on the surface= GM

--------

R²

where G is universal gravitational constant

G = 6.67408 × 10^-11 m3 kg-1 s-2

Where M is mass of planet Mars

M = 6.42 × 10^23 kg

where R is the radius of planet Mars

R = 3370 km

= 3370000m

Acceleration due to gravity= GM

---------

R²

= [( 6.67408 × 10^-11) ( 6.42 × 10^23)]

----------------------------------------------------

( 3370000)²

solve further and that's it.

hope is helps
