1. An infinitely long wire carriesuniformstatic electric charge of line density λ.
a. Find the electric fieldEat a distance a vertically above themid-point of thewire.
b. If the length of the wire is 2aandan identical wire is placed at right angle from one end of thewire,Find the E at point P which is equidistant from both wiresanddistance a perpendicular to both wires.(seefigure)
