The de Broglie wavelength associated with a ball of mass 1 ~kg having kinetic energy 0.5 ~J is
Options
- A6.626 10⁻³⁴ ~m
- B13.20 10⁻³⁴ ~m
- C10.38 10⁻²¹ ~m
- D6.626 10⁻³⁴ A .
Correct answer
A. 6.626 10⁻³⁴ ~m
Step-by-step solution
Kinetic energy = 1 2 m v^2 [m=mass, v= velocity ] or, 0.5= 1 2 1 v^2 or, v=1 ~ms ⁻¹ . de Broglie wavelength, = h m v or, = 6.626 10⁻³⁴ Js 1 ~kg 1 ~ms ⁻¹ =6.626 10⁻³⁴ ~m .
