Question

As weight of an object on a planet upon the gravity (g = GM/R square) which depent upon the mase of planet & its
radius. As the mass of moon is 1/100th of the mass of the years and it's radius is 1/4th
that of the earth ,gravity of moon is 1/6th that of earth,
1/6th.​

Answer 1

Answer:

Acceleration due to gravity on the earth's surface is g=

=(1/80)×(4)

=1/5

or g

m

=g/5

Answer 2

Answer:

g on moon is 1.6345m/s²

Explanation:

g on earth = 9.807m/s²

g on moon = 1/6 of g on earth

= (1/6)×9.807

= 1.6345m/s²

so if u need to calculate the weight of a body having mass , on any planet , just multiply the mass of the body with the rate of acceleration due to gravity of that planet .

weight = mg.

hope it helped .

thanks .
