An α- particle moves in a circular path of radius 0.83 cm in the presence of a magnetic field of 0.25 Wb/m². The de-Broglie wavelength associated with the particle will be

1 A^o

0.1 A^o

10 A^o

0.01 A^o

Solution

0.01 A^o

We knows
$straight R equals space mv over qB and space straight lambda space equals space straight h over mv straight lambda space equals fraction numerator space straight h over denominator qBR end fraction space equals space fraction numerator 6.6 space straight x space 10 to the power of negative 34 end exponent over denominator 1.6 space straight x space 10 to the power of negative 19 end exponent space straight x space 0.83 space straight x space 10 to the power of negative 2 end exponent space straight x space 0.25 space end fraction space 0.01 space straight A to the power of straight o$
