If z1 lies on absz=1 and z2 lies on absz...

If `z_1` lies on `absz=1` and `z_2` lies on `absz=2` then

A

`oo`

B

`0`

C

`1`

D

`2`

Text Solution

Verified by Experts

The correct Answer is:
C

Let`z= x +iy`. So
`|z-1| = |z+1| rArr Re(z) =0 rArrx le 0`
`|z -1| = |z + i| rArr x = y`
` |z+1| = |z-i| rArr y = - x`
Only (0,0) will satisfy all conditions.
Therefore, the number of complex numbers(z) is 1.
