MCQ

The general solution of differential equation is $(y + c)^2= cx$ where ccis an arbitrary constant. The order and degree of the differential equation are respectively:

✓
$1, 2$
B
$2, 2$
C
$1, 1$
D
$2, 1$

✓

Answer

Correct option: A.

$1, 2$

Given equation is
$=(\text{y}+\text{c})^2=\text{cx}$
$\Rightarrow\text{y}=\sqrt{\text{cx}}-\text{c}$
$\Rightarrow\frac{\text{dy}}{\text{dx}}=\frac{\sqrt{\text{c}}}{\text{x}}$
$\Rightarrow\Big(\frac{\text{dy}}{\text{dx}}\Big)^2=\frac{\text{c}}{\text{x}}$
The order of differential equation is the order of the highest derivative in the equation is $1$
The degree of differential equation is the power of the highest order derivative in the equation is $2$
