A gas is taken through the cycle \(A \rightarrow B \rightarrow C \rightarrow A\), as shown in figure. What is the net work done by the gas?
- A \(2000 \mathrm{~J}\)
- B \(1000 \mathrm{~J}\)
- C Zero
- D \(-2000 \mathrm{~J}\)
Answer & Solution
Correct Answer
(B) \(1000 \mathrm{~J}\)
Step-by-step Solution
Detailed explanation
Net work done by the gas \(=\) Area enclosed in \(p-V\) curve, i.e. area of \(\triangle A B C\). \(W_{\text {net }}=\frac{1}{2} \times 5 \times 10^{-3} \times 4 \times 10^5 \mathrm{~J}=10^3 \mathrm{~J}=1000 \mathrm{~J}\)
