Just plot B/R vs r/R. I'm assuming that R is a constant?

I think that this might work, but I think the way that we should approach it is to use the fact that we know that the function and the Fourier transform are even, and then we are allowed to do the following: \int_0^{\infty}dx J_0(x) = \frac{1}{2} \int_{-\infty}^{\infty}dx J_0(x) Then we can...

I seem to see a problem with the first integration, over x. There should be i and k terms coming down from that integration, sadly. Unless I'm making a silly mistake.

Doesn't Parseval's relation relate to the Modulus Squared of the function and its Fourier transform?

theres the gravity force and there is the force of friction at the point of contact between the sphere and the surface.

If the surface is less than vertical, the ball will roll down it, otherwise, it will fall.
