Question

Calculate the acceleration due to gravity on the surface of Mars having a mass of (6.4 × 10)23 kg and a radius of (3.37×10 )6

Answer 1

We can find the acceleration due to gravity on the surface of Mars from the formula:
g_Mars=(GM_Mars)/(R_Mars^2 ),
here, G is the universal gravitational constant, M_Mars is the mass of the Mars, R_Mars is the radius of the Mars.
Then, we get:
g_Mars=(GM_Mars)/(R_Mars^2 )=(6.67∙〖10〗^(-11) (Nm^2)/〖kg〗^2 ∙6.4∙〖10〗^23 kg)/(3.37∙〖10〗^6 m)^2 =3.758 m/s^2 .
