MCQ
Work done in the cyclic process shown in figure is ...........
- A$4 P_0 V_0$
- B$-4 P_0 V_0$
- ✓$-\frac{22}{7} P_0 V_0$
- D$-13 P_0 V_0$
✓
Answer
Correct option: C.
$-\frac{22}{7} P_0 V_0$
c
(c)
(c)
Cyclic process is anticlockwise then
Work done $=-$ (Area of $P-V$ graph $)$
$W=-\pi R_1 R_2$
$=-\pi\left(\frac{3 P_0-P_0}{2}\right) \times\left(\frac{3 V_0-V_0}{2}\right)$
$=\frac{-22}{7} P_0 V_0$
