Answer 1

Answer:

3ab/2

Explanation:

the graph F-x graph gives the work done.the, area between the the graph line and x-axis is work done.

the graph is F=x

b=a

so,

work done= integration of b

=b²/2

now putting the limits from -a to 2a

=(2a)²/2 - (-a)²/2

=2a² - a²/2

=3a² /2

but we know that b=a (from the graph)

=3ab/2
