MCQ
Area between the curves $y = x^3$ and $y = \sqrt x$ is
  • A
    $\frac{5}{3}$
  • B
    $\frac{5}{4}$
  • $\frac{5}{12}$
  • D
    None

Answer

Correct option: C.
$\frac{5}{12}$
c
The curve $y=\sqrt{x}$ is $y^{2}=x ;(y \geq 0) \quad \ldots$ $(i)$

and $y=x^{3}$      .....$(ii)$

Point of intersection are $(0,0) \&(1,1)$

$\therefore $ Required area $ = \int\limits_0^1 {\left( {{{\rm{y}}_2} - {{\rm{y}}_1}} \right)dx} $

$ = \int\limits_0^1 {\left( {\sqrt x  - {x^3}} \right)dx} $

${=\frac{5}{12}}$
