Problem 2:

      Find the elevation h (km) where the weight of an object is one-tenth (1/10) its weight on the surface of the earth.m_e = 5.9742x10²⁴ kg; r_e = 6,378 km

Problem 3:

      Two identical asteroids travel through space side by side while touching each other.  If the asteroids are composed of homogeneous pure iron (ρ = 7,874kg/m³) and are spherical, what diameter in meters and milesmust they have for their mutual gravitational attraction to be 5 N?
