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 $x = 1 m$ to $x = 5 m$ will be

Options:

Answer:

Solution:

Work done = force x displacement

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

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