An -particle moves in a circular path of radius 0.83 ~cm in the presence of a magnetic field of 0.25 ~Wb / m ^2 . The de-Broglie wavelength associated with the particle will be

Options

  1. A1 Å
  2. B0.1 Å
  3. C10 Å
  4. D0.01 Å

Correct answer

D. 0.01 Å

Step-by-step solution

We knows R= m v q B aligned & = h m v & = h q B R & = 6.6 10⁻³⁴ 1.6 10⁻¹⁹ 0.83 10⁻² 0.25 & =0.01 Å aligned
