Solving a Differential Equation with Boundary Conditions

Click For Summary
SUMMARY

The differential equation presented is \(\frac{d^2 r}{ds^2} + \frac{m}{r^2} - \frac{nr}{3} = 0\) with boundary conditions \(r = a\) when \(s = 0\) and \(\frac{dr}{ds} = 0\) when \(r = b\). To solve this equation, it is recommended to multiply the entire equation by \(\frac{dr}{ds}\) and then integrate. This method effectively simplifies the problem and allows for the application of the given boundary conditions.

What is the answer of this differential equation.

((d^2) r)/((ds)^2) +(m/(r^2)) -(nr/3)=0

the boundary conditions (i) r=a when s=0 and (ii) dr/ds =0 when r=b.

m and n are constants.

hi kumudumalee! welcome to pf! :smile:

(try using the X2 button just above the Reply box :wink:)

multiply the whole equation by dr/ds, and then integrate :smile:
 
Thanks...
