WBJEE 2020 Physics Solved Paper

Consider an engine that absorbs 130 cal of heat from a hot reservoir and delivers 30 cal heat to a cold reservoir in each cycle. The engine also consumes 2J energy in each cycle to overcome friction. If the engine works at 90 cycles per minute, what will be the maximum power delivered to the load ? [Assume the thermal equivalent of heat is 4.2J/cal]
