Option: 1

300R \; In2


Option: 2

2+2 \; In2


Option: 3

300R \; In2-4R

 


Option: 4

300R \; In2+4R

Answer (4)

T=300+2V

Work done W=\int pdv

          =\int \frac{\left ( 300+2V \right )}{V}Rdv \begin{bmatrix} PV=nRT\\ P=\frac{RT}{V} \end{bmatrix}

         =300 \; R\; In\left ( 4-2 \right )+2\left ( 4-2 \right )R

         =300 \; R\; In 2+4R
