A point charge is moving with speed u between the wires in the same plane at a distance X1 from one of the wires. When the wires carry current of magnitude I in the same direction , the radfius of curvature of the path of the point charge is R1. In contrast, if the currentsd I in the two wires have directions opposite to each other, the radius of curvature of the path is R2. if X0/X1 = 3, the value of R1/R2 is
