An ideal gas has undergone through the cyclic process as shown in the figure. Work done by the gas in the entire cycle is ______ \(\times 10^{-1} \mathrm{~J}\).
(Take \(\pi=3.14\))
- A 310
- B 314
- C 320
- D 319
Answer & Solution
Correct Answer
(B) 314
Step-by-step Solution
Detailed explanation
Area of circle, \(\mathrm{W}=\frac{\pi}{4} \mathrm{~d}_1 \mathrm{~d}_2\) \(\mathrm{W}=\frac{\pi}{4}(500-300) \times 10^3(350-150) \times 10^{-6}\) W = 31.4 Joule \(\mathrm{W}=314 \times 10^{-1} \mathrm{Joule}\)
