Ques 1) Find the electric field vector at P (a,a,a) due to three infinitely long lines of charges along x,y and z - axes respectively. The charge density i.e is charge per unit length of each wire is @.
Ques 2) A system consists of a thin charged wire ring of radius r and a very long uniformly charged wire oriented along the axis of the ring, with one of it's ends coinciding with the centre on the ring. The total charge on the ring is q nad linear charge density on the straight wire is @ . Evaluate the interaction force b/w the ring and the wire.
