If R is the radius of the Earth then the height above the Earth's surface at which the acceleration due to gravity decreases by `20%` is

If R is the radius of the earth , the height from its surface at which the acceleration due to gravity is 9% of its value at the surface is

If the radius of the earth is R , the height above the surface of the earth where the acceleration due to gravity will be 1% of its value on the earth's surface is

At a height equal to earth's radius, above the earth's surface, the acceleration due to gravity is

At which height from the earth's surface does the acceleration due to gravity decrease by 75 % of its value at earth's surface ?

At which height from the earth's surface does the acceleration due to gravity decrease by 75 % of its value at earth's surface ?

At which height from the earth's surface does the acceleration due to gravity decrease by 75 % of its value at earth's surface ?

At what height from the surface of earth, the acceleration due to gravity decreases by 2% ? [Radius of earth = 6,400 km.]

If 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 4% of its value on the surface of the earth is
