In the x-y-plane, the region y>0 has a uniform magnetic field B 1 k ^ and the region y<0 has another uniform magnetic field B 2 k ^ . A positively charged particle is projected from the origin along the positive y-axis with speed V o = π m/s at t = 0, as shown in the figure. Neglect gravity in this problem.

Two parallel wires in the plane of the paper are distance X0 apart. 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
