Question

At what altitude the value of g should become 1/4 on the surface of eartH
al

Answer 1

Answer:

The height above the Earth's surface where the acceleration due to gravity at sea level reduce to 0.20% is 136090931 m=136090.931 km 136090931 m = 136090.931 k m..

Answer 2

g'=g(1-2h/R)

g/4=g(1-2h/R)

1/4=1-2h/R

2h/R=3/4

8h=3R

h=3R/8

h=3/8×6 378.1 kilometers

h=2391.7875kilometers
