An astronaut carried a pot containing soil weighing 60N from the earth to the surface of moon. He kept it there and just before return from moon to the earth he weighed the soil there on the surface of the moon and found that it was only 10N. Where did the rest of the soil go and how much mass of soil was lost ?( gearth =10m/s square , gmoon =gearth/6 )
As it is given that gmoon =gearth/6
we can directly substitute the values given as
gmoon =gearth/6
= 60/6
= 10N
therefore it is proved that g of moon is 10N
So the rest of the soil has gone nowhere and no mass of it was lost. The weight was different as the acceleration due to gravity of the earth is different from that of the moon.
