The order of the differential equation of all parabolas, whose latus rectum is 
and axis parallel to the 
-axis, is
Text Solution
Verified by ExpertsThe correct answer is:
D
: Equation of the family of such parabolas is
where 
and 
are arbitrary constants.
On differentiating (i) w.r.t. 
, we get
On differentiating (ii) w.r.t. 
, we get
On putting value of 
from (ii) in (iii), we get
Hence the order of required differential equation is 2 .
