At what height over the earth's pole, the free fall acceleration decreases by one percent (assume the radius of earth to be 6400 km )

At what height over the Earth's pole the free-fall acceleration decreases by one per cent, by half?

At what height above the earth’s surface does the force of gravity decrease by 10% ? Assume radius of earth to be 6370 km.

At what height from the surface of earth, the acceleration due to gravity decreases by 2% ? [Radius of earth = 6,400 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 distance above the surface of Earth the acceleration due to gravity decreases by 10% of its value at the surface? (Radius of Earth = 6400 km)

At what height above the surface of the earth will the acceleration due to gravity be 25% of its value on the surface of the earth ? Assume that the radius of the earth is 6400 km .

At what height above the surface of the earth will the acceleration due to gravity be 25% of its value on the surface of the earth ? Assume that the radius of the earth is 6400 km .

Acceleration due to gravity is g on the surface of the earth. Then the value of the acceleration due to gravity at a height of 32 km above earth's surface is : (Assume radius of earth to be 6400 km)
