Question

If z lies on the circle ½z½=1, then fraction numerator 2 over denominator z end fraction lies on

  1. circle    
  2. straight line    
  3. parabola    
  4. none of these    

The correct answer is: straight line


    fraction numerator 2 over denominator z end fraction equals fraction numerator 2 stack z with ̄ on top over denominator vertical line z vertical line to the power of 2 end exponent end fraction equals 2 stack z with ̄ on top Þ straight line
    Hence (b) is the correct answer.
