1. Two spherical objects have masses 447 kg and 285 kg.  Their centers are separated by a distance of 27 m.  Find the gravitational attraction between them.

2.Two celestial bodies have masses 3.26 x 105 kg and 6.65 x 103 kg.  The gravitational attraction between them is 61.1 N.  How far apart are their centers?

3.Two asteroids have equal masses and experience a gravitational force of 29.2 N towards one another.  Their centers are 38.4 m apart.  Determine each of their masses.

4.A 8.15 kg object is located at a distance of 6.47 x 103 km from the center of a larger object whose mass is 5.55 x 1024 kg.  What is the size of the force acting on the smaller object?

All of these equations are solved using the following equation: (from the internet)

In each question , you are given all but one of the variables......plug in the values and solve for the unknown variable....

Example: 1      M1 = 447 kg      M2 =285 kg    r = 27 m     and G is given above....plug in all of the values and solve for  Fgrav

WATCH out on the last question   distance given is KILOmeters....convert to meters to use in the equation !!!

All of the questions can be answered with the following equation....you are given all of the variables except one.....plug in the given numbers and solve for the unknown:

In each question , you are given all but one of the variables......plug in the values and solve for the unknown variable....
