Question

Work done in the cyclic process shown in figure is :

• A. $4P_0{V}_0$
• B. $-4P_0{V}_0$
• C. $-\frac{22}{7}{P}_0{V}_0$
• D. $-13P_0{V}_0$

Answer 1

Answer: (C)

$-\frac{22}{7}{P}_0{V}_0$

Workdone in cyclic process is in anticlockwise direction is negative of area of cyclic process $=\pi \left(P_o\right)\left(V_o\right)$
$[\therefore$ Area of ellipse $=\pi ab]$
So, workdone in cyclic process $=-\left(\frac{22}{7}\right)P_o{V}_o[\because \pi =\frac{22}{7}]$
