Question

HURRY GUYS I WILL MARK AS BRAINLIEST
If z lies on a circle | z-1|= 1 then (z - 2)/|z| is

Answer 1

Let 2/z= t , such that z=2/t

Take mod both sides

|Z| =|2/t|=1

Or |2|/|t|=1

Or |t|=2

Which will represent a circle centred at origine and having radius is equal to 2.

Answer 2

Answer:

0/2

Step-by-step explanation:

If |z-1| is equal to 1, then

|z| = 1+1

z = 2

Substitute z=2 in the second equation

(2-2)/2 = 0/2 = 0
