Two charged particle A and B each of charge +e and masses 12 amu and 13 amu respectively follow a circular trajectory in chamber X after the velocity selector as shown in the figure. Both particles enter the velocity selector with speed 1.5 × 106 ms–1. A uniform magnetic field of strength 1.0 T is maintained within the chamber X and in the velocity selector.
