Document Summary

F = ma = (charge)(electric field) o: finding e. Superposition of electric fields (non point charges) o. 6 o o: electric field lines, demonstrates the direction of a system of electric fields, an individual electric field is tangent to any point on a line, electric field lines bunched together means e is strong. Where a is the area vector, v is the uniform velocity, or electric field, flowing: v dot a through that area o electric flux of a uniform, flat surface = electric field x area (cos(angle)) 10: flux is - if the a vector is choosen to point in the opposite direction of e, 1d - linear charge denisty. = charge/length electric flux = enclosed charge/constant independent of the radius: for any closed surface, 2d - surface charge denisty. = charge/area r^-2 r^-1: 3d - volume charge denisty. = charge/volume: gauss"s law r^0 = 1, for a closed spherical surface o.
