Document Summary
Z : distance along the axis from the center of the disk. R : radius of the disk: : surface charge density. Force on a point charge in an electric field. F has same direction as e" if q is . Electric dipole of moment i" placed in electric field e" Dipole has potential energy u assoc . with orientation in field. U = 0 when i: u is least with e is t to e" - pet when p" aligned ( u - U is greatest l u - opposite e" Oi =qq. no# to = net flux of the electric field through the surface. Electric flux through a gaussian surface : An excess charge on an isolated is located entirely on conductor the outer surface of the conductor. Electric field due to infinite line of charge. R = perpendicular distance from the line of charge to the point. Electric field due to an infinite nonconducting sheet.
