Question

at what altitude the acceleration due to gravity reduces to half of its value as that on the surface of the earth? take radius of earth as 6.4*10'6 m, g on the surface of earth as 9.8 m/s'2

Answer 1

The acceleration due to gravity at a height 1/20 th radius of the earth above the earth's surface is 9 m/s2. Find the value of acceleration due to gravity at an equal distance below the surface of the earth. Given the radius of the earth = 6400 km

Answer 2

I found it :)
