Q1 A ring of radius R is given a charge Q and kept in Y-Z plane and an infinite wire of charge density is kept on X- axis starting from center of ring.What will be the force of interaction (magnitude and direction both) on ring due to wire?

Q2 A thin glass rod is bent into a quarter circle of radius r  and placed in XY plane + Q charge is uniformly distributed on the rod.What will be electric field vector at point O(Origin)??
