Application +4 | -1

z_1+z_2+z_3=0

and

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

, then value of

z_1^2+z_2^2+z_3^2

equals

View answer and explanation

Correct option: B

Option B (0) is correct because using the given condition

z_1 + z_2 + z_3 = 0

and the fact that

|z_i| = 1

, the expression simplifies to zero.
