If `w=(z+4i)/(z+2i)` is purely imaginary then find `|z+3i|.`

If (z-1)/(z-i) is purely imaginary then find the minimum value of abs(z-(3+3i))

If (z - i)/(z +1) is purely imaginary then the locus of z = x +iy is

if the number (z-2)/(z+2) is purely imaginary then find the value of |z|

If (z-i)/(z+1) is purely imaginary then the locus of z = x + iy is

If (z+i)/(z+2i) is purely real then find the locus of z

If (z-i)/(z+i) (z ne -i) is a purely imaginary number, then z. bar(z) is equal to

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

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=x+iyand(z-i)/(z+1) is purely imaginary, then show that the point z always lies on a circle.
