WebMeasuring electrical field experimentally is quite difficult and could provide a real challenge even to the most advanced electrical engineers, physicists, and other experts involved, I understand the electric field cancellation in a spherical surface because of the symmetry of the configuration. Electric field due to infinite line charge can be expressed mathematically as, E = 1 2 o r Here, = uniform linear charge density = constant of permittivity of free space and r = radial distance of point at distance r from the wire. And these two 'chunks' will create their fields of equal magnitude but opposite direction, and therefore will cancel out to reveal 0 total electric field at the origin. But the direction is from negative charge to positive charge. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Its unit is Coulomb meter.
