Q.
In the indicator diagram, net amount of work done will be
A) Positive
B) Zero
C) Infinity
D) Negative
Explanation
(a) Figure shows that loop 1 is anticlockwise, therefore $W_{1}$ is negative, loop 2 is clockwise, therefore $W_{2}$ is positive.
Also, loop 2 is bigger
$\therefore\ \ W_{2} > W_{1}$
Hence, $W = {- W}_{1} + W_{2} \rightarrow$positive
