z_1, z_2

are complex numbers such that

\operatorname{Re}\left(z_1\right)=\left|z_1-2\right|

\operatorname{Re}\left(z_2\right)=\left|z_2-2\right|

and

\arg \left(z_1-z_2\right)=\pi / 3

, then

\operatorname{Im}\left(z_1-z_2\right)=

View answer and explanation

Correct option: B

4 / \sqrt{3}

Option B (

4 / \sqrt{3}

) is correct. By using the given conditions and properties of complex numbers, we can find the imaginary part of the difference between the two complex numbers.
