A gas undergoes a cyclic process `ABCDA` as shown in the figure. The part `ABC` of process is semicircular. The work done by the gas is

A

`400 pi J`

B

`2456 J`

C

`200 pi`

D

`1826 J`

Text Solution

Verified by Experts

The correct Answer is:
c
`W = Area ABCDA = (pi R^(2))/(2)`
`=(11xx(20)^2)/(2) = 200 pi Joule`.
