- A \(10^7 \pi \mathrm{~J}\)
- B \(10^4 \pi \mathrm{~J}\)
- C \(10^2 \pi \mathrm{~J}\)
- D \(10^{-3} \pi \mathrm{~J}\)
Answer & Solution
Correct Answer
(C) \(10^2 \pi \mathrm{~J}\)
Step-by-step Solution
Detailed explanation
For cyclic process, \(\begin{aligned} & \mathrm{Q}=\mathrm{W}=\text { Area of } \mathrm{p} \text {-v diagram } \\ & =\frac{\pi}{4} \times 20 \times 10^3 \times 20 \times 10^{-3}=10^2 \pi \mathrm{~J} \end{aligned}\)
