Understanding +4 | -1

Let

3 - i

and

2 + i

be affixes of two points

A

and

B

the argand plane and

P

represents the complex number

z = x + i\;y.

Then, the locus of

P

if

\left| {z - 3 + i} \right| = \left| {z - 2 - i} \right|

is

View answer and explanation

Correct option: C

The perpendicular bisector of

AB

Option C (The perpendicular bisector of

AB

) is correct because the equation

\left| {z - 3 + i} \right| = \left| {z - 2 - i} \right|

represents the locus of a point

P

such that its distance from

A

and

B

are equal, which is the perpendicular bisector of

AB

.
