A cyclic process for an ideal gas is shown in figure . Given `W_(AB) = +700 J , W_(BC) = +400J , Q_(CA) = -100J`.

The efficiency of the cycle is -

A

`100%`

B

`83.44%`

C

`85.71%`

D

`81.11%`

Text Solution

Verified by Experts

The correct Answer is:
C
`eta = (W_("net"))/(Q_("input")) xx 100 = (600)/(700) xx 100 = (600)/(7) = 85.71%`
