If the efficiency of an engine is 50 % and its work output is 500 J , then find input.

Options

  1. A1000 J
  2. B500 J
  3. C100 J
  4. D250 J

Correct answer

A. 1000 J

Step-by-step solution

Efficiency, = Workdone Heat input 100 or 100 = Work done Heat input = 500 Heat input Heat input = 500 100 50 =1000 ~J
