The de Broglie wavelength associated with a ball of mass

200 {~g}

and moving at a speed of

5 {~m} / {h}

, is of the order of

\left({h}=6.625 \times 10^{-34} {Js}\right.

)

View answer and explanation

Correct option: C

10^{-25} {~m}

Option C (

10^{-25} {~m}

) is correct because it calculates the de Broglie wavelength using the formula

\lambda = \frac{{h}}{{mv}}

with appropriate unit conversions.
