Question

The approximate value of g at an altitude above Earth equal :to one Earth diameter is

Answer 1

Answer:

to one Earth diameter is 1.09 m/s^2

Explanation:

Hey buddy,

g' = g/9 = 1.09 m/s^2

Explaination-

Gravitational acceleration due to earth at distance r from earth's centre is given by

g = GM/r^2

At height equal to earths diameter

h = 2R

r = R+h = R+2R = 3R

Gravitational acceleration at h=2R

g' = GM/9R^2

g' = g/9

g' = 9.8/9

g' = 1.09 m/s^2

Gravitational acceleration at height equal to earths diameter is 1.09 m/s^2.
