Question

Figure shows the F-x graph. Where F is the force applied and x is the distance covered

by the body along a straight line path. Given that F is in newton and x in metre, what is the work done ?

  1. 10 J    
  2. 20 J    
  3. 30 J    
  4. 40 J    

The correct answer is: 10 J


    Work done = area under curve and displacement axis
    =1 cross times 10 minus 1 cross times 10 plus 1 cross times 10 equals 10   J
