Directions: Solve the following problems applying the Law of Universal
Gravitation.
1. Two spherical objects have masses of 250 kg and 600 kg. Their centers are
separated by a distance of 50 m. Find the gravitational attraction between
them.
2. Two spheres of equal mass have a force of gravity of 7x10-°N exerted on
each other. If the distance between them is 7m, find the mass.
3. Two spherical objects have masses of 3.0 x 105 kg and 7.5 x 10° kg. The
gravitational attraction between them is 265 N. How far apart are their
centers?
4. Compute "g" for the surface of a planet whose radius is twice that of the
Earth and whose mass is the same as that of the Earth. (Note that "g" on
the Earth's surface has a magnitude of 9.8 m/s2.)
5. Compute "g" for the surface of Mercury. Its radius is 2.4 x10 m and its mass
is 3.3 x 1023 kg.
