The figure shows two infinite lines of charge A and B in the plane of paper Both lines are uniformly charged Linear charge density of A is while that of B is A The lines are at a normal separation a with x and y axes as shown and taking z axis to be along the outward normal to the plane of paper electric field strength at any point a 2 0 z can be expressed as 4a2 A 2 e a 42 8a C 4 a 42 2a B 48 a 42 D none of these
