Let O be the vertex and Q be any point...

Let O be the vertex and Q be any point on the parabola,`x^2=""8y` . It the point P divides the line segment OQ internally in the ratio 1 : 3, then the locus of P is :

A

`x^(2)=y`

B

`y^(2)=x`

C

`y^(2)=2x`

D

`x^(2)=2y`

Text Solution

Verified by Experts

The correct Answer is:
D
4 Let P be (h,k).
`:." "h=t`
`andk=(t^(2))/(2)`
`:." "k=(h^(2))/(2)`
`rArr2y=x^(2)`,
which is required locus.
