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

A what height above the earth's surface the value of g becomes 25% of its value on the earth if radius of the earth is 6400km.

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