Question

An astronaut travels to a position in space that is a height of 2R above the surface of the earth, where R is earths radius.At this height, the force of earths gravity is ____ of its force at the surface.

A.1/8
B.1/9
C.1/4
D.1/3​

Answer 1

1/8

Step-by-step explanation:

2R is the same as 1D, so you are a full diameter above yhe earth. The diameter of the earth is 12,742km, space starts at 100km so it probably isn't a third or a quarter. it is most likely an 1/8 or 1/9. if I had to guess it would be 1/8
