In the cyclic process given in the P - V diagram, the work done is
Options
- A( P₂-P₁ 2 )^2
- B( V₂-V₁ 2 )^2
- C( P ₂ ~V ₂- P ₁ ~V ₁ )
- D4 (P₂-P₁ ) (V₂-V₁ )
Correct answer
D. 4 (P₂-P₁ ) (V₂-V₁ )
Step-by-step solution
From diagram, aligned & major axis, 2 ~b = V ₂- V ₁ b = V ₂- V ₁ 2 & minor axis, 2 a = P ₂- P ₁ a = P ₂- P ₁ 2 & Work done = Area of cyclic work = ab & = ( P ₂- P ₁ 2 ) ( V ₂- V ₁ 2 ) & = 4 ( P ₂- P ₁ ) ( V ₂- V ₁ ) aligned
