Hi i am in ap physics and we just finished the electric charges and electric fields chapter but i am completely clueless. I haven't been keeping up with the problems and haven't been to a lot of classes and now it has come back to haunt me. Any good sites out there or can anyone answer some of my questions about these topics? I don't really get these chapters at all.
For example: 2 indentical conducting spheres, fixed in place, attract each other with an electrostatic force of .108 N when separated 50cm. The spheres are then connected by a thin conducting wire. When the wire is removed, the spheres repel each other with an electorstatic force of .0360 N. What were the initial charges on the spheres? Answer is -1 and 3 mirco columbs but i don't know how to get it.
This is the easiest question out of all of my set and i hope if i can understand this the rest will click 2. Also, any good resources on Electirc field due to point, line, disk, charges? thanks in advance
