de-Broglie wavelength associated with a ball of mass 1 ~kg having kinetic energy 0.5 ~J is

Options

  1. A6.63 10⁻³⁰ ~m
  2. B6.63 10⁻³⁴ ~m
  3. C1.32 10⁻³³ ~m
  4. D1.32 10⁻³⁴ ~m

Correct answer

B. 6.63 10⁻³⁴ ~m

Step-by-step solution

de-Broglie wavelength, = h p = h 2 m K Here, m=1 ~kg , K=0.5 ~J aligned & h=6.63 10⁻³⁴ ~J ~s , =? & = 6.63 10⁻³⁴ 2 1 0.5 =6.63 10⁻³⁴ ~m aligned
