NEET Solved Paper 2014 Question 18
Question: A thermodynamic system undergoes cyclic process ABCDA as shown in figure. The work done by the system in the cycle is [AIPMT 2014]
Options:
A) $ p _0V _0 $
B) $ 2p _0V _0 $
C) $ \frac{p _0V _0}{2} $
D) zero
Show Answer
Answer:
Correct Answer: D
Solution:
Work done in the cyclic process = Area bound by the closed configuration
= Area of closed configuration = $ 2[ \frac{1}{2}(v _{0/2})\times p _0 ]+{ -2[ \frac{1}{2}(v _{0/2})p _0 ] . } $ = zero.
