Let

z_1, z_2, z_3

be three complex number such that

z_1+z_2+z_3=0

and

\left|z_1\right|=\left|z_2\right|=\left|z_3\right|=1

, then

\left|z_1^2+2 z_2^2+z_3^2\right|

equals

View answer and explanation

Correct option: A

Option A (1) is correct because using the given conditions, we can simplify the expression to |z_2|^2 which is equal to 1.
