At what depth below the surface does the acceleration due to gravity becomes 70% of its value in the surface of earth ?

How much below the surface of Earth does the acceleration due to gravity become 70% of its value on the surface of Earth. Radius of Earth = 6.4 xx 10^(6) m .

How much below the surface of the earth does the acceleration due to gravity becomes 70% of its value at the surface of earth ? (Take R_(e)=6400 km)

How much below the surface of the earth does the acceleration due to gravity becomes 70% of its value at the surface of earth ? (Take R_(e)=6400 m)

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.]

At what depth below the surface of earth the acceleration due to gravity becomes one-third of its value at the surface of earth ?

How far away from the surface of earth does the acceleration due to gravity become 4% of its value on the surface of earth ? [R_(e )=6400 km]

How far away from the surface of earth does the acceleration due to gravity become 4% of its value on the surface of earth ? [R_(e )=6400 km]

How much below the surface of the earth does the acceleration due to gravity become 70% of its value at the surface of the earth ? Radius of the earth is 6400 km

Calculate the depth below the surface of the earth where acceleration due to gravity becomes half of its value at the surface of the earth . Radius of the earth = 6400 km.
