Hi, there,

Could you please show me the solution to Griffiths Introduction to Electrodynamics, problem 2.26? The integral is so complicated. Thanks

Cool! We're using the same textbook. Yeah, my next assignment will probably have problems from that section as well, since we're covering chapter 2 in the lectures right now. But, no one's going to do your hw for you. Show what you've got so far, and they'll help you out with corrections/point you in the right direction.

You might need to post the problem, since many you could help you may not have that text.

The problem is

A conical surface (an empty ice-cream cone) carries a uniform surface charge <sigma>. The height of the cone is h, and the radius of the top is R. Find the potential difference between points a(the vertex) and b (the center of the top)

Thanks a lot.

It could be worse!

I remember one post that said, in it's entirety, "What's the solution to the fourth problem on today's homework."

And another "What chapters will tomorrows test cover?"
