Two infinitely long thin straight wires having uniform linear charge densities lambda and 2lambda are arranged parallel to each other at a distance r apart.The intensity of the electric field at a point midway between them is

(i) Two infinitely long line charges each of linear charge density lambda are placed at an angle theta as shown in figure. Find out electric field intensity at a point P, which is at a distance x from point O along angle bisector of line charges.
