if z is a complex number such that mod[(z-5i)/(z+5i)]=1 then locus of z is........

straight line , more precisely the real axis itself.

mod(z-5i)=mod(z+5i)
thus z is a complx no. lying on d perp. bisector of the line joining 5i and -5i..... thus z is any point on d real axis of d argand plane......

the real axis in d argand plane=x axis.....
the imaginary axis is the y axis....

corrct ans is real or X axis...the given locus represents the bisector of the two points 5i and -5i...
