Document Summary
Density 2 . direction is radial . E = : a = 4 v2 . N-=qq- deperidson sizeof surface . orientation of surface relative to light intensity of light passing through surface . N ( fun directly proportional to no . of field lines passing through the surface) At = az lost . ( constant electricfield) = ea (for uniform sphere) (cid:15482) hemisphere = 2^-82. 92 (cid:8869) 10=0 ( cause the lines entering sphere the so net is also zeros teen it, C- = 2k = 2 ? just the . The total fuun is fun through the barrel of cylinder . Electric dipole field lines: direction of is direction of, magnitude of is proportional to the density of field lines . field lines (cid:15483) Field strongest in between the charges . E- day : dac law and dipoles .
