Let `z!=i` be any complex number such that `(z-i)/(z+i)` is a purely imaginary number. Then `z+ 1/z` is

If z is a complex number such that (z-1)/(z+1) is purely imaginary, then the value of |z| is-

If z is a complex number such that frac{z-1}{z+1} is purely imaginary, then

If z(!=-1) is a complex number such that (z-1)/(z+1) is purely imaginary,then |z| is equal to

If z_1, z_2 are complex number such that (2z_1)/(3z_2) is purely imaginary number, then find |(z_1-z_2)/(z_1+z_2)| .

If z_1, z_2 are complex number such that (2z_1)/(3z_2) is purely imaginary number, then find |(z_1-z_2)/(z_1+z_2)| .

If z_1, z_2 are complex number such that (2z_1)/(3z_2) is purely imaginary number, then find |(z_1-z_2)/(z_1+z_2)| .

If z is a complex number such that (z-i)/(z-1) is purely imaginary, then the minimum value of |z-(3 + 3i)| is :
