A coordinate system (in meters) is constructed on the surface of a pool table, and

three objects are placed on the coordinate system as follows: a 0.8 kg object at the origin,

a 2.8 kg object at (0 m,1.7 m), and a 4.4 kg

object at (3.8 m,0 m).

Find the resultant gravitational force exerted on the object at the origin by the other

two objects. The universal gravitational con-stant is 6.672 × 10-11N · m2/kg2

.
