Two metal spheres, each of mass 18 g and initially at rest, are dropped from a height of 9 m in an evacuated chamber. one sphere has a charge of +70 μc, and the other has a charge –70 μc. find the difference in final speeds of the two spheres (the speeds just before each one hits the ground). assume that there is a downward electric field of about 150 v/m near the earth’s surface.

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!
