Nobody? Am atleast on the right track? I wish there was a way to check these sort of problems.

Fixed, thanks

Im including a scan of the problem and my work, please let me know if I did this right. Sorry about the sloppy handwriting. http://img244.imageshack.us/img244/6521/strengthsproblem3rk.th.jpg http://img241.imageshack.us/img241/8866/strengthsworkedout1rw.th.jpg

I got it, wow. that took forever. Thanks for all the help. On another note, I was studying the problem because the teacher hinted off that he was going to quiz us on it during the next class. Well, today was quiz day and he gave us a centroid problem, yeah a freakin centroid. Haha, easy A

Please help, I think I am missing something simple.

I took your advice and this is where I got. The book gives an answere of 17.2 and I am getting 16.3. What I am a doing wrong? http://www.streetneeds.com/uploads/auser/statics4.jpg

I went to both of those sites and I couldn't find the information. If someone could give me a visual process of what I have to do (equations etc), I can probably pick it up. I am a visual learner. I have to see the process done before I can repeat it.

whoa, I didnt mean to do that, sorry

Thanks for the replies. Im still not having any luck, I need a new major:(

Sorry, make it 5. 5. A pair of parallel plates, forming a capacitor, are charged. The plates are pulled apart to double the original separation, the charges on the plates remaining the same. What is the ratio of the final energy stored to the original energy stored?

Im doing some homework problems and I cannot figure out how to do these for the life of me. Any help would be appreciated. 1. An airplane is flying through a thundercould at a height of 2000 m. If there is a charge concentration of +40 C at 3000 , within the cloud and -40 C at height 1000 m...
