Consider the parabolas `S_(1)=y^(2)-4ax=0` and `S_(2)=y^(2)-4bx=0.S_(2)` will `S_(1),` if

A

`agtbgt0`

B

`bgtagt0`

C

`agt0, blt"but |b|"gta`

D

`alt0, bgt"but |b|"gta`

Text Solution

Verified by Experts

The correct Answer is:
B
If a and `bgt0,` then graphic representation would be as follws :

`S_(2)" will contain "S_(1),`
`"if latusrectum of "S_(2)gt"latusrectum of "S_(1)`
`rArr" "4bgt4a`
`:." "bgtagt0`
