Intuitively I know it's zero, but when I applied that to the gravitational law, I got confused.

Is the value of g at the center of the Earth zero or infinite ?

My calculus is so basic

Hey PF, I've studied electrostatics and electrodynamics in the past years in high school, but it was just school-study I never had a chance to thoroughly understand them, I'd like to read and learn more about electrostatics and electrodynamics on my holiday, so I'd like anyone to...

Where can I get that kind of help from ?? Can I ask on physics forums for that kind of help ??

Experts like engineers ?

I'm an international student, living in a developing country, so I don't have much on my resume except for some great grades, but other than that nothing, competitions, and extracurricular activities aren't offered much in my country so I think ISEF is my only hope now. :sad:
