The length of perpendicular from P(2-3i)...

The length of perpendicular from `P(2-3i)` on the line `(3+4i)Z + (3-4i)bar Z+9=0` is equal to

A

9

B

`9//4`

C

`9//2`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
C

Let PM be the required length. Then,
PM =`(|(2-3i)(3-4i)+(3-4i)(2+3i)+9|)/(2|3-4i|)`
`rArr` PM `=45/10=9/2`
