If the relation between subnormal SN and subtangent ST at any point S on the curve
by 2 = (x + a) 3 is p(SN) = q(ST) 2 , then p/q =
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
by 2 = (x + a) 3 differentiating both sides
2by 
= 3(x + a)
2 .1
= 
length of subnormal = SN = y 
= 
and length of subtangent = ST = y 
= 
= 
(given)
= 
= 
{using by 2 = (x + a) 3 = 
=
