Have you tried using Gauss's Law?

anonymous · Answer

I'm confused with that.

Teheh, you're school student? What grade?

anonymous · Answer

thats not then answer.

anonymous · Answer

Actually, i was planning to explain gauss law. But depends on your grade. If you're school student, i can't use multiple integral then. But okay, bye.

anonymous · Answer

Yes im in school. who else does problems like this?
