Three masses lie on the x$-$axis. Object A is at the origin and has a mass of $829\mathrm{.}1$ kg$.$ Object B has a mass of $321$ kg and is located $5\mathrm{.}6$ meters in the positive x direction from A$.$ Finally, object C$,$ which has a mass of $618\mathrm{.}4$ kg$,$ is positioned $4\mathrm{.}7$ meters from object B$,$ so that object B is between objects A and C$.$ What is the force acting on object B$?$
