If a foot of the normal from the point to a circle is and is a diameter of the circle, then the equation of circle is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(C)
Step-by-step Solution
Detailed explanation
Given, the normal from the point 4, 3 to a circle is 2, 1. So, the equation of this normal is y-1=3-14-2x-2 ⇒ y=x-1 ...1, As, the normal at any point to the circle passes through its centre. And, we have a given diameter…
