  1. Q

    This one has bothered me for a while (electric field)

    well, the force acting on the bigger sphere is just the repulsion force between the two spheres, but how can i find the electric field between them when i only know the charge of the smaller sphere?

    This one has bothered me for a while (electric field)

    basically i have a small charged sphere on the left, and at a certain horizontal distance away from it theres a bigger sphere that is made of a thin shell of nonconducting material. the bigger sphere (B) is hanging from a non conducting, uncharged thread, and that thread makes an angle of 20...

    Net Flux due to charge on surface

    hmm... i never knew that could happend, i thought it would either contribute to the flux or has nothing to do with it. thanks!

    Another Net charge question

    thanks DOC Al and jtbell! thats exactly what i needed to know but wasnt sure about!

    Another Net charge question

    well, if theres a charged sphere, like a mouse ball, but the outside of it is wrapped in rubber, which will insulate it, would there be an electric field on the surface of the rubber?

    Another Net charge question

    If the field is zero at all points on a surface, does this mean there is no net charge enclosed by the surface? I thought if you had an insulator of some kind wrapping around the charged particle, it could have those properties. but i also feel that electric field will go through insulator..(...

    Net Flux due to charge on surface

    Hello, Will a point charge directly on the surface affect the net flux through the surface? (will it contribute to the next flux like a point inside the surface? i thought about it, and it seems like it will produce the same # of electric field lines going in as going out, so would it...
