If R is the radius of the earth, the height at which g will decrease by `0.1%` of its value at the surface of the earth is

If R is the radius of earth , the height ,at which the weight of a body becomes 1/4 of its weight on the surface of earth , is

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

If radius of earth is R , then the height h at which the value of g becomes (1/49)th of its value at the surface is

If radius of earth is R , then the height h at which the value of g becomes (1/49)th of its value at the surface is

If R is the radius of the earth, then the value of acceleration due to gravity at a height h from the surface of the earth will become half its value on the surface of the earth if

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 1% of its value from the surface of the earth is

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 .
