Question

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.

  1. Electric field across the conducting plate of the velocity selector is – 106 NC–1 stack i with hat on top    
  2. Electric field across the conducting plate of the velocity selector is 106 NC–1 stack i with hat on top    
  3. The ratio r subscript A end subscript divided by r subscript B end subscript of the radii of the circular paths for the two particles is 12/13.    
  4. The ratio r subscript A end subscript divided by r subscript B end subscript of the radii of the circular paths for the two particles is 13/12.    

The correct answer is: The ratio r subscript A end subscript divided by r subscript B end subscript of the radii of the circular paths for the two particles is 12/13.
