An ideal gas underoges cyclic process of ABCDA as shown in Given `P-V` diagram (figure) The amount of work done by the gas isA. 6PoVoB. `-2PoVo`C. `+2 PoVo`D. `+4 PoVo`

Answer» Correct Answer - B
Consider the p-V diagram given in the question. Work done in the process ABCD=-area of reactangle ABCDA.
`(AB)xxBC=(3V_(0)-V_(0))xx(2P_(0)-P_(0))`
`=2V_(0)xxP_(0)=2P_(0)V_(0)`
As the process is going anit -clockwise, hence there is a net compression in the gas, So, work done by the gas `=-2P_(0)V_(0)`
