A) \[{{t}_{2}}=-{{t}_{1}}-\frac{2}{{{t}_{1}}}\]
B) \[{{t}_{2}}=-{{t}_{1}}+\frac{2}{{{t}_{1}}}\]
C) \[{{t}_{2}}={{t}_{1}}-\frac{2}{{{t}_{1}}}\]
D) \[{{t}_{2}}={{t}_{1}}+\frac{2}{{{t}_{1}}}\]
Correct Answer: A
Solution :
Equation of normal at a point () on a parabola is . Equation of the normal at point on parabola is It also passes through , then NOTE If a normal drawn at a point \[{{t}_{1}}\] on the parabola meets the parabola again at a point \[{{t}_{2}}\], thenYou need to login to perform this action.
