Question

A cyclic process is shown in the figure. Work done by the syatem during the cyclic process $ABCDA$ is

• A. $160J$
• B. $150J$
• C. $600J$
• D. $900J$

Answer 1

Answer: (B)

Work done during the cyclic process $ABCDA$
= area enclosed by $ABCDA$
$=\left(\frac{\text{AB}+\text{CD}}{2}\right)\times \text{AD}$
$=\frac{\left(2+1\right)}{2}\times 10^2$
$=1\text{.}5\times 10^2\text{J}$
$=150J$
