Question
The relation between the displacement X of an object produced by the application of the variable force F is represented by a graph shown in the figure. If the object undergoes a displacement from 
to 
the work done will be approximately equal to
- 16 J
- 32 J
- 1.6 J
- 8 J
The correct answer is: 16 J
Work done = Area under curve and displacement axis
= Area of trapezium
= 
×(sum of two parallel lines) × distance between them
= 
= 
= 14 J
As the area actually is not trapezium so work done will be more than 14 J i.e. approximately 16 J
