If $|z-3 i|+|z+5 i|=4$,then the locus of $z$ is

The minimum value of $|2z - 1| + |3z - 2|$ is

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

The locus of the point $z=x+iy$ satisfying the equation $\left|\frac{z-1}{z+1}\right|=1$ is given by :

If $a$ and $c$ are complex numbers and $b$ is a real number in the Argand plane,then the perpendicular distance from $c$ to the line $a \bar{z} + \bar{a} z + b = 0$ is

$z_1$ and $z_2$ are two fixed points on the Argand plane. If $z$ is a complex number such that $|z-z_1| + |z-z_2| = \lambda$,then the locus of $z$ is
