Question

The cyclic process form a circle on a pV diagram as shown in figure. The work done by the gas is
A. (a) `pi/4(p_2-p_1)^2`
B. (b) `pi/4(V_2-V_1)^2`
C. (c) `pi/2(p_2-p_1)(V_2-V_1)`
D. (d) `pi/4(p_2-p_1)(V_1-V_2)`

Answer 1

Correct Answer - D
`W=-pi(Radius)^2`
`=-pi(Radius)(Radius)`
`=-pi((p_2-p_1)/(2))((V_2-V_1)/(2))`
