normal
In the following indicator diagram, the net amount of work done will be
A
Positive
B
Negative
C
Zero
D
Infinity
Solution
Work done during process $1$ is positive while during process $2$ it is negative, because process $1$ is clockwise while process $2$ is anticloc wise. But area enclosed $P-V$ graph (i.e., work done) in process $1$ is smaller, so net work done will be negative.
