Homework Statement Cell membranes (the walled enclosure around a cell) are typically about 7.5 nm thick. They are partially permeable to allow charged material to pass in and out, as needed. Equal but opposite charge densities build up on the inside and outside faces of such a membrane, and...

thank you so much

Why the field lines are always perpendicular to the conducting line?

Suppose that a point charge q is located at some distance d from a grounded conducting plane. How do we find the force acting on the charge due to the presence of the conducting plane and what could be its direction? Thanks..

If we suppose that the magnitudes of the charge distributions on the two rings are different. Is the mid line still an equipotential line? How can we explain this situation? Thanks..
