From a point \((C, 0)\) three normals are drawn to the parabola \(y^2=x\). Then,

  1. A \(C < \frac{1}{2}\)
  2. B \(C=\frac{1}{2}\)
  3. C \(C>\frac{1}{2}\)
  4. D \(\frac{1}{2}>C>\frac{1}{4}\)
Verified Solution

Answer & Solution

Correct Answer

(C) \(C>\frac{1}{2}\)

Step-by-step Solution

Detailed explanation

Given, \(y^2=x\) \[ \therefore \quad 4 a=1 \Rightarrow a=\frac{1}{4} \] Any normal to the parabola is \[ y=m x-2 a m-a m^3 \] If it passes through \((C, 0)\), then If it passes through \((C, 0)\), then…
