A body of mass x ~kg is moving with a velocity of 100 ~ms ⁻¹ . Its de-Broglie wavelength is 6.62 10⁻³⁵ ~m . Hence, x is ( h =6.62 10⁻³⁴ Js . )

Options

  1. A0.1 ~kg
  2. B0.25 ~kg
  3. C0.15 ~kg
  4. D0.2 ~kg

Correct answer

A. 0.1 ~kg

Step-by-step solution

aligned &= h mv &= 6.62 10⁻³⁴ 6.62 10⁻³⁵ 100 &=0.1 ~kg aligned
