The radius of moon is 27% of the earth radius and its mass is 1.2 % of the earth mass find the acc due to gravity on surface of moon?

2 answers

gravitational force between two masses is directly proportional to the product of the masses, and inversely proportional the the square of the distance between them

g-moon = g-earth *.012 / .27^2
The radius of moon is 27% of the Earth's radius and it's mass is 1.2% of the earth mass find the acceleration due to gravity on the surface of the moon .How much will a 424N body weigh there?
