Chapter 5: Q.18 (page 128)

Exercises 18 show two of the three forces acting on an object in equilibrium. Redraw the diagram, showing all three forces. Label the third force F3鈫�.

Short Answer

Expert verified

The net force of F3鈫�should be acting on the object such that the object is at equilibrium.

Step by step solution

01

Given information:

From the given diagram, one can observe thatF1>F2.

02

Draw the force diagram with net force:

The net force acting on the given diagram is

F=F1 + F2

Since both the forces are in opposite directions, the net force will be reduced and acting along F1.

It can be seen from the below force diagram:

03

Draw the force diagram for F3:

Since the net force is along F1, the third force F3 should act in such a direction to nullify the net force F.

Therefore, the F3 must be acting along F2 as shown in the below force diagram:
