The circle \(x^2+y^2+3 x-y+2=0\) cuts an intercept on \(X\)-axis of length
- A 3
- B 4
- C 2
- D 1
Answer & Solution
Correct Answer
(D) 1
Step-by-step Solution
Detailed explanation
Given equation of circle is \(x^2+y^2+3 x-y+2=0\). On comparing this equation with \(x^2+y^2+2 g x+2 f y+c=0\), we get \(g=\frac{3}{2}, f=-\frac{1}{2}\) and \(c=2\) Now, the length of intercept on \(\mathrm{X}\)-axis \(=2 \sqrt{g^2-c}\)…
