A sample of an ideal gas is taken through the cyclic process ABCA as shown in figure. It absorbs, $\displaystyle 40$ J of heat during the part AB, no heat during BC and rejects $\displaystyle 60$ J of heat during CA. A work of $\displaystyle 50$ J is done on the gas during the part BC. The internal energy of the gas at A is $\displaystyle 1560$ J . The workdone by the gas during the part CA is :
Official answer
(2)
$\displaystyle 30$ J
