At what height above the earth surface, the value of g is half of its value on earth's surface ? Given its radius is 6400 km

At what height above the earth's surface, the value of g is same as in mine 80 km deep?

At what height above the earth's surface does the value of g becomes 36% of the value at the surface of earth ?

At what height above the earth's surface, the value of g is same as that at a depth of 100 km ?

At what height above the earth's surface the acceleration due to gravity will be 1/9 th of its value at the earth’s surface? Radius of earth is 6400 km.

At what height above the earth's surface is the acceleration due to gravity 1% less than its value at the surface ? [R = 6400 km]

At what height h above the earth's surface, the value of g becomes g/2 (where R is the radius of the earth)

The value of 'g' at a certain height above the surface of the earth is 16% of its va lue on the surface. The height is (R = 6300 km)

The height at which the value of g is half that on the surface of the earth of radius R is

At what height from Earth's surface the acceleration due to gravity becomes 20% of its value on the surface of earth. [Radius of earth = 6,400 km.]
