Identify and sketch all the external forces acting on the chair. because the chair can be represented as a point particle of mass m, draw the forces with their tails centered on the black dot in the middle of the chair. be certain to draw your forces so that they have the correct orientation.

 The two forces will act on the chair i.e. and .

Further Explanation:

Free body diagram is the graphical representation or illustration of all the forces applied on the body with their directions. This helps us to visualize all the applied forces on the body with their directions and make us possible to solve complex problems based on kinematics.

The normal force which is always perpendicular to the surface of the object and there is force due to gravity of the earth which pulls the object toward the center of the earth given by . Its magnitude depends upon the mass of the body and expressed as mg. Here, the term is called acceleration due to gravity and it has a constant value of .

Concept:

The chair is represented as a point particle of mass .

The diagram is drawn as shown in Figure 1.

The chair has two forces acting in two directions, upward and downward direction.  

•The upward normal force or the reaction force.

•The downward force due to gravity of the earth.

The normal force is equal to the magnitude of the force due to gravity but opposite in direction to balance the force due to gravity.

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

answer; how far out of place which the object finished relative to the starting location;
