Complex Numbers 2 Question 25
26.
$\min _{z \in s}|1-3 i-z|$ is equal to
(a) $\frac{2-\sqrt{3}}{2}$
(b) $\frac{2+\sqrt{3}}{2}$
(c) $\frac{3-\sqrt{3}}{2}$
(d) $\frac{3+\sqrt{3}}{2}$
Show Answer
Answer:
Correct Answer: 26. (c)
Solution:
- $\min _{Z \in}|1-3 i-z|=$ perpendicular distance of point $(1,-3)$
from the line $\quad \sqrt{3} x+y=0 \Rightarrow \frac{|\sqrt{3}-3|}{\sqrt{3+1}}=\frac{3-\sqrt{3}}{2}$
