Q.
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?
A) $10\ J$
B) $20\ J$
C) $30\ J$
D) $40\ J$
Explanation
(a) Work done = area under curve and displacement axis
$= 1 \times 10 - 1 \times 10 + 1 \times 10 = 10\ J$
