Question

if mass of the moon=
$7.4 \times {10}^{22}kg$
radius of moon=
$1.7 \times {10}^{6}m1$
then the acceleration due to gravity is​

Answer 1

Answer:

The acceleration due to gravity on moon is 1.71 m/s^2

Explanation:

We know,

Gravitational constant, G = 6.673×10^-11 m^3 kg^-1 s^-2

Given,

Mass of moon, M = 7.4×10^22

Radius of moon, R = 1.7×10^6

We know,

g = GM/R^2

= (6.673×10^-11 × 7.4×10^22) / (1.7×10^6)^2

= (4.94×10^12) / (2.89×10^12)

= 1.71 m/s^2
