Question

calculate the value of acceleration due to gravity on the surface of moon

mass of moon= 7.4 × 10^22 kg

radius of moon= 1740 km

G= 6.7 × 10^-11 Nm^2 kg^-2
​

Answer 1

Answer:

gm=GM/R^2

gm/ge=M/Me×{Re/Rm}^2

gm=ge×M/Me×{Re/Rm}^2

=9.8×7.4×10^22×6.4×6.4×10^6×10^6÷

6×10^4×1.74×1.74×10^6×10^6

gm=1.63m/s^2

The value of gm on the moon is 1.63m/s^2
