Question

The order and degree of the differential equation $r=\frac{{\left[1+{\left(\frac{dy}{dx}\right)}^2\right]}^{3/2}}{\frac{d^{2}y}{d{x}^2}}$ are respectively

• A. 2,2
• B. 2,3
• C. 2,1
• D. 1,4

Answer 1

Answer: (A)

${\left(\frac{d^{2}y}{d{x}^2}\right)}^2{r}^2={\left[1+\left(\frac{dy}{dx}\right)\right]}^3$
order : 2
degree : 2
