A sample of ideal gas is expanded to twice its original volume of  1m3 in quasistatic process for which  P=αV2 with α=3×105Pa/m6 as shown in figure. Work done by the expanding gas is


 

a
7×105J
b
3×105J
c
6×105J
d
8×105J

detailed solution

Correct option is A

Work done, W=∫V1V2 αV2dVW=αV3312=3×1053×23−13W=7×105J
