Question

(c) How close to the line segment do you have to be so that the field is within 5% of that from an infinite line charge?

A segment of line charge density dq/4 pi element 0r^2 ). dq = pt X l is constant the field approaches that of a point charge (i.e I right arrow 0 in such a way that L right arrow Infinity the field approaches that of an infinite line charge. (c) How close to the line segment do you have to be so that the field is within 5% of that from an infinite line charge? (d) Show that as Show that as pt C/m is E at a point a meters from the center of the segment. (b) The electric field at a distance a from an infinite line charge density Pt Coulombs per meter is L meters long (from -L/2 to +L/2). (a) By integrating, calculate

Explanation / Answer

3.1 Electric Flux density

In (approximately) 1837, Michael Faraday, being interested in static electric fieldsand the effects which various insulating materials (or dielectrics) had on these fields,devised the following experiment:

Faraday had two concentric spheres constructed in such a way that the outer onecould be dismantled into two hemispheres. With the equipment taken apart, the innersphere was given a known positive charge. Then, using about 2 cm of
