The relationship between the force $F$ and position $x$ of a body is as shown in the figure. The work done in displacing the body from $x = 1m$to $x = 5m$ will be

Step-by-step solution

Work done = force x displacement



= area of ABNM + area of CDEN + area of EFGH + area of HIJ - area of OAM

$= \dfrac{-1}{2} \times 1 \times 10 + 1 \times 5 \times 5 + \dfrac{1}{2} \times 1 \times 10 = 20\text{J}$
