In one dimensional case, the relationship between force and position is shown in the figure. The work done by the force in displacing a body from $x = 1\, cm$ to $x = 5\, cm$ is ............ $\mathrm{ergs}$

A

$20$

B

$60$

C

$70$

D

$700$

Solution

$W = 10\times1 + 20\times1 -20\times1 + 10\times1 = 20\, erg$
