Question

In Find the maximum angle of deviation for a prism with angle A equals 60 to the power of ring operator end exponent and mu = 1.5, If a constant magnetic field of strength 10 to the power of negative 4 end exponentT is applied parallel to the metal surface, then the radius of the largest circular path followed by the electrons will be :

  1. 0.04 m    
  2. 0.04 cm    
  3. 0.04 mm    
  4. 0.04 km    

The correct answer is: 0.04 m


    Radius of largest circular path followed by the electrons
    r equals fraction numerator m v over denominator e B end fraction equals fraction numerator 9.1 cross times 1 0 to the power of negative 31 end exponent cross times 7.036 cross times 1 0 to the power of 5 end exponent over denominator 1.6 cross times 1 0 to the power of negative 19 end exponent cross times 1 0 to the power of negative 4 end exponent end fraction = 0.04 m
