JEE Main 2 April 2026, Shift 2, Maths Q2

Question 2 of 75 in this shift, Maths question 2 of 25, Section A.

Let the circles

C_1: |z| = r

and

C_2: |z - 3 - 4i| = 5, z \in \mathbb{C}_e

be such that

C_2

lies within

C_1

. If

z_1

moves on

C_1

z_2

moves on

C_2

and

\min|z_1 - z_2| = 2

, then

\max|z_1 - z_2|

is equal to:

(1) $12$
(2) $17$
(3) $22$ Official answer
(4) $24$
