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 cross times 10 to the power of 6 end exponent m s to the power of negative 1 end exponent. 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 negative 10 to the power of 6 end exponent N C to the power of negative 1 end exponent stack i with tilde on top    
  2. Electric field across the conducting plate of the velocity selector is 10 to the power of s end exponent N C to the power of negative 1 end exponent stack i with tilde on top    
  3. The ratio fraction numerator T subscript A end subscript over denominator r subscript B end subscript end fraction of the radii of the circular paths for the two particles is 12/13    
  4. The ratio fraction numerator T subscript A end subscript over denominator r subscript B end subscript end fraction of the radii of the circular paths for the two particles is 13/12    

The correct answer is: The ratio fraction numerator T subscript A end subscript over denominator r subscript B end subscript end fraction of the radii of the circular paths for the two particles is 12/13
