The area enclosed between the parabolas y 2 = 4ax and
x 2 = 4by is -
A
ab
B
ab
C
ab
D
None of these
Text Solution
Verified by ExpertsThe correct answer is:
B
y 2 = 4ax … (1)
x 2 = 4by … (2) 
Using (2) in (1) 
= 4ax ⇒ x = 0 or x 3 = 64ab 2 i.e.
x = 0, 4a 1/3 b 2/3 .
∴ Required area = 
– 
dx
= 
ab. (on calculation)
