Calculate the force of gravity on the 0.50-kg mass if it were 6.4×106 m above earth's surface (that is, if it were two earth radii from earth's center).

Radius of Earth is given as

now here the height from the surface of earth is same as that of radius

now here the acceleration due to gravity at this height is given as

now the force of gravity on the given object will be

so the force of gravity on it is 1.225 N

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !

h o h o hope you have a merry christmas!
