If two distinct chords of a parabola , passing through
are bisected on the line
, then length of the latus rectum can be less than..........
2
4
1
None
Any point on the line can be taken
equation of the chord, with this as mid point is
it passes through
So,
, this should have two distinct real roots so,
so, length of latusrectum < 4.
