At what height from the surface of earth the gravitation potential and the value of g are −5.4×107 Jkg−2 and 6.0 ms−2 respectively? Take the radius of earth as 6400 km.
At what height from the surface of earth, the gravitational potential and the value of g are −5.4×107 J/kg2 and 6m/s2 respectively [take the radius of earth as 6400 km]
Calculate acceleration due to gravity at a height of 2000 km above the Earth's surface. Mass of Earth = 6×1024 kg, radius of Earth = 6.4×106 m and (Gravitational constant, G =6.7×10−11Nm2kg−2)
At what height above the surface of the earth, the value of g becomes 64% of its value on the surface is the earth? (Radius of the earth is 6400km )
If the acceleration due to gravity, g, is 10m/s2 at the surface of the earth (radius 6400km), then at a height of 1600km the value of g will be? (in m/s2)
Gravitational potential of the body of mass m at a height h from surface of earth of radius R is (Take g= acceleration due to gravity at earth's surface)
