I have this question that I am struggling to see if it is correct or not.
A quantity y(r) satisfies the first-order fifferential equation r^2*dy/dr = K where r > 0 and K is a constant.
The general solution I got from this FO differential equation is: y = K(-1/r + F)
The second part to this question is to find a particular solution for y(R) = 0, where R is a constant.
I seem to get 0 as R = 1/F which cancels out everything.
Much appreciated for anyone that can help.
