Let

P

be the point (1,0) and

Q

a point on the locus of

{y^2} = 8x,\;\;

The locus of mid point of

PQ

View answer and explanation

Correct option: D

{y^2} - 4x + 2 = 0

Option D (

{y^2} - 4x + 2 = 0

) is correct because it represents the locus of the midpoint of PQ, derived by substituting the coordinates of a general point on the parabola into the midpoint formula.
