Question

Is the radius of the earth is 6400 km the height above the surface of the Earth where the value of acceleration due to gravity will be 1% of its value from the surface of the earth

Answer 1

Decreases by 1 % g' = 99/100g

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

99/100 = (1-2h/R)

2h/R = 1 - 99/100

2h/R = 1/100

h = R/200

h = 6400/200

h = 32 km
