Answer:

The work done by the particle during its displacement of 12 m is 13 J.

Explanation:

Given: Force = F

 displacement = d (values as shown in attached file)

To find: The work done during the given displacement.

Solution: #For work done, we know that:

            W = Area of force-displacement graph

So, we find the area of force-displacement graph for the numerical values of work done.

           Area = area of rectangle + area of triangle

[Refer to the attached image]

           Area = 4 × 2 + 1/2 × 2 × 5

           Area = 8 + 5

           Area = 13 J = Work done

Hence, the work done by the particle during its displacement of 12 m is 13 J.
