The work done in the process AB is

A

`8xx10^5J`

B

`10xx10^5J`

C

`7xx10^5J`

D

`12xx10^5J`

Text Solution

Verified by Experts

The correct Answer is:
D
On `P-V` diagram area below the process gives work done.
`DeltaW_(AB)=[(1)/(2)(1+3)xx(3-1)+3xx(5-3)+(1)/(2)(1+3)(6-5)]xx10^5`
`=(4+6+2)xx10^5=12xx10^5J`
